Rexroth MAL Introduction to the Product

1-1

1 Introduction to the Product

1.1 Description

Asynchronous motors of the Rexroth MAL series have been designed as direct drives for printing presses. They are characterized by the following (and other) features:

• Air-cooled housing motor

• Hollow shaft with limited traversing distance

• Cylindrical roller bearing with regreasing option

• Encoder unit, mounted outside to the impression cylinder

The motors are coupled to the printing press via a customer-specific shaft coupling which must be mounted by the user before he starts up the motor. The driven shaft of the impression cylinder is passed through the hollow shaft of the motor and onto the moving shaft coupling. The large inside diameter of the hollow shaft of the motor allows swivel movements of the driven shaft of the impression cylinder. Here, it is particularly important to ensure that the displacement of the rotor generated by the swivel movement is less than the maximum permissible traversing distance of the rotor. The user is responsible for meeting and ensuring this requirement.

3.5 Protection Against Contact with Electrical Parts

Note: This section refers to equipment and drive components with voltages above 50 Volts.

Touching live parts with voltages of 50 Volts and more with bare hands or conductive tools or touching ungrounded housings can be dangerous and cause electric shock. In order to operate electrical equipment, certain parts must unavoidably have dangerous voltages applied to them.

DANGER

High electrical voltage! Danger to life, severe bodily harm by electric shock!

⇒ Only those trained and qualified to work with or on electrical equipment are permitted to operate, maintain or repair this equipment.

⇒ Follow general construction and safety regulations when working on high voltage installations.

⇒ Before switching on power the ground wire must be permanently connected to all electrical units according to the connection diagram.

⇒ Do not operate electrical equipment at any time, even for brief measurements or tests, if the ground wire is not permanently connected to the points of the components provided for this purpose.

⇒ Before working with electrical parts with voltage higher than 50 V, the equipment must be disconnected from the mains voltage or power supply. Make sure the equipment cannot be switched on again unintended.

⇒ The following should be observed with electrical drive and filter components:

⇒ Wait thirty (30) minutes after switching off power to allow capacitors to discharge before beginning to work.

Measure the voltage on the capacitors before beginning to work to make sure that the equipment is safe to touch.

⇒ Never touch the electrical connection points of a component while power is turned on.

⇒ Install the covers and guards provided with the equipment properly before switching the equipment on.

Prevent contact with live parts at any time.

⇒ A residual-current-operated protective device (RCD) must not be used on electric drives! Indirect contact must be prevented by other means, for example, by an overcurrent protective device.

⇒ Electrical components with exposed live parts and uncovered high voltage terminals must be installed in a protective housing, for example, in a control cabinet.

To be observed with electrical drive and filter components:

3-6

DANGER

High electrical voltage on the housing!

High leakage current! Danger to life, danger of injury by electric shock!

⇒ Connect the electrical equipment, the housings of all electrical units and motors permanently with the safety conductor at the ground points before power is switched on. Look at the connection diagram. This is even necessary for brief tests.

⇒ Connect the safety conductor of the electrical equipment always permanently and firmly to the supply mains. Leakage current exceeds 3.5 mA in normal operation.

⇒ Use a copper conductor with at least 10 mm² cross section over its entire course for this safety conductor connection!

⇒ Prior to startups, even for brief tests, always connect the protective conductor or connect with ground wire.

Otherwise, high voltages can occur on the housing that lead to electric shock.

3.6 Protection Against Electric Shock by Protective Low Voltage (PELV)

All connections and terminals with voltages between 0 and 50 Volts on Rexroth products are protective low voltages designed in accordance with international standards on electrical safety.

WARNING

High electrical voltage due to wrong

connections! Danger to life, bodily harm by electric shock!

⇒ Only connect equipment, electrical components and cables of the protective low voltage type (PELV = Protective Extra Low Voltage) to all terminals and clamps with voltages of 0 to 50 Volts.

⇒ Only electrical circuits may be connected which are safely isolated against high voltage circuits. Safe isolation is achieved, for example, with an isolating transformer, an opto-electronic coupler or when battery-operated.

3.7 Protection Against Dangerous Movements

Dangerous movements can be caused by faulty control of the connected motors. Some common examples are:

• improper or wrong wiring of cable connections

• incorrect operation of the equipment components

• wrong input of parameters before operation

• malfunction of sensors, encoders and monitoring devices

• defective components

Rexroth MAL Safety Instructions for Electric Drives and Controls

3-7

• software or firmware errors

Dangerous movements can occur immediately after equipment is switched on or even after an unspecified time of trouble-free operation.

The monitoring in the drive components will normally be sufficient to avoid faulty operation in the connected drives. Regarding personal safety, especially the danger of bodily injury and material damage, this alone cannot be relied upon to ensure complete safety. Until the integrated monitoring functions become effective, it must be assumed in any case that faulty drive movements will occur. The extent of faulty drive movements depends upon the type of control and the state of operation.

DANGER

Dangerous movements! Danger to life, risk of injury, severe bodily harm or material damage!

⇒ Ensure personal safety by means of qualified and tested higher-level monitoring devices or measures integrated in the installation. Unintended machine motion is possible if monitoring devices are disabled, bypassed or not activated.

⇒ Pay attention to unintended machine motion or other malfunction in any mode of operation.

⇒ Keep free and clear of the machine’s range of motion and moving parts. Possible measures to prevent people from accidentally entering the machine’s range of motion:

- use safety fences - use safety guards - use protective coverings

- install light curtains or light barriers

⇒ Fences and coverings must be strong enough to resist maximum possible momentum, especially if there is a possibility of loose parts flying off.

⇒ Mount the emergency stop switch in the immediate reach of the operator. Verify that the emergency stop works before startup. Don’t operate the machine if the emergency stop is not working.

⇒ Isolate the drive power connection by means of an emergency stop circuit or use a starting lockout to prevent unintentional start.

⇒ Make sure that the drives are brought to a safe standstill before accessing or entering the danger zone. Safe standstill can be achieved by switching off the power supply contactor or by safe mechanical locking of moving parts.

⇒ Secure vertical axes against falling or dropping after switching off the motor power by, for example:

- mechanically securing the vertical axes

- adding an external braking/ arrester/ clamping mechanism

- ensuring sufficient equilibration of the vertical axes The standard equipment motor brake or an external brake controlled directly by the drive controller are not sufficient to guarantee personal safety!

3-8

⇒ Disconnect electrical power to the equipment using a master switch and secure the switch against reconnection for:

- maintenance and repair work - cleaning of equipment

- long periods of discontinued equipment use

⇒ Prevent the operation of high-frequency, remote control and radio equipment near electronics circuits and supply leads. If the use of such equipment cannot be avoided, verify the system and the installation for possible malfunctions in all possible positions of normal use before initial startup. If necessary, perform a special electromagnetic compatibility (EMC) test on the installation.

3.8 Protection Against Magnetic and Electromagnetic Fields During Operation and Mounting

Magnetic and electromagnetic fields generated near current-carrying conductors and permanent magnets in motors represent a serious health hazard to persons with heart pacemakers, metal implants and hearing aids.

WARNING

Health hazard for persons with heart

pacemakers, metal implants and hearing aids in proximity to electrical equipment!

⇒ Persons with heart pacemakers, hearing aids and metal implants are not permitted to enter the following areas:

- Areas in which electrical equipment and parts are mounted, being operated or started up.

- Areas in which parts of motors with permanent magnets are being stored, operated, repaired or mounted.

⇒ If it is necessary for a person with a heart pacemaker to enter such an area, then a doctor must be consulted prior to doing so. Heart pacemakers that are already implanted or will be implanted in the future, have a considerable variation in their electrical noise immunity. Therefore there are no rules with general validity.

⇒ Persons with hearing aids, metal implants or metal pieces must consult a doctor before they enter the areas described above. Otherwise, health hazards will occur.

Rexroth MAL Safety Instructions for Electric Drives and Controls

3.12 Protection Against Pressurized Systems

Certain motors and drive controllers, corresponding to the information in the respective Project Planning Manual, must be provided with pressurized media, such as compressed air, hydraulic oil, cooling fluid and cooling lubricant supplied by external systems. Incorrect handling of the supply and connections of pressurized systems can lead to injuries or accidents. In these cases, improper handling of external supply systems, supply lines or connections can cause injuries or material damage.

CAUTION

Danger of injury by incorrect handling of pressurized systems !

⇒ Do not attempt to disassemble, to open or to cut a pressurized system (danger of explosion).

⇒ Observe the operation instructions of the respective manufacturer.

⇒ Before disassembling pressurized systems, release pressure and drain off the fluid or gas.

⇒ Use suitable protective clothing (for example safety glasses, safety shoes and safety gloves)

⇒ Remove any fluid that has leaked out onto the floor immediately.

Note: Environmental protection and disposal! The media used in the operation of the pressurized system equipment may not be environmentally compatible. Media that are damaging the environment must be disposed separately from normal waste.

Note: The achievable torque depends on the drive controller used.

The reference value for the characteristic curves of the motor is a non-stabilized DC bus voltage of 540VDC.

Explanation:

Start of a drop in speed and power before the rated speed nN is reached.

This behavior is called de-rating and occurs only with some versions of motor windings. With no de-rating, key speed equals rated speed.

Until the key speed is reached, continuous current at standstill I1 applies (effective value). With no de-rating, the continuous current at standstill equals the rated current IN.

Until the key speed is reached, continuous torque at standstill M1 is available for S1 operation. With no de-rating, the continuous torque at standstill equals the rated torque MN.

With de-rating effective, the torque is reduced once the key speed is reached. Fig. 4-4 shows two characteristic curves starting at the key speed.

With no de-rating effect, induction motors provide a constant torque until the rated speed (rated torque); starting at the rated speed, constant performance rated power PN is available.

The speed limit up to which a motor can be safely operated. Normally limited by the mechanical construction (bearing) or by the use of a holding brake.

6 Type Code MAL130

6.1 Introduction

Rexroth MAL is the product name of the asynchronous hollow-shaft motors from REXROTH.

The type code describes the available motor variants; it is the basis for selecting and ordering products from BOSCH REXROTH. This applies to both new products as well as spare parts and repairs.

The following descriptions provide an overview of the separate columns of the type code (”abbrev. column”) and their meaning.

Note: When selecting a product, please always consider the detailed specifications in chapter 4 ”Technical Data” and chapter 9

”Notes Regarding Application”.

1. Product

MAL is the name of the product group of air-cooled asynchronous motors with hollow shaft, which are designed as rotary cylindric drives for printing presses.

2. Frame size

The motor frame size is specified according to the axle height. The axle height is the distance from the center of the shaft to the foot bearing surface. In the case of MAL motors, the size specification is determined from the corresponding measurement and rounding to the closest standard axle height.

Available sizes: MAL130.

3. Frame Length

Within a series, the graduation of increasing motor frame length is indicated by ID letters in alphabetic order. The higher the motor frame length, the higher the continuous torque.

Available frame length: E.

4. Winding Code

Winding codes serve to differentiate winding variants from one another and indicate the rated speed.

Example: The rated speed for the winding ”0075” is n_N = 750 min^-1. The DC bus voltage of 540 V_DC is a fixed reference value.

A drive combination is selected on the basis of the corresponding selection data and operating characteristics.

5. Type of Cooling

In general, MAL motors are equipped with an axial-flow fan for operation with surface cooling.

Operation without cooling is not permissible.

6. Motor Encoder

MAL motors are delivered without motor encoder, as the encoder is integrated into the machine. The motor encoder is selected and applied by the machine manufacturer.

7. Electrical Connection

The electrical connection is established via a flanged socket with outgoing feeder toward the A-side of the motor.

As a counterpart, the flanged socket requires a plug which is not included in the scope of delivery. Preferably, ready-made cables of BOSCH REXROTH with completely mounted plug should be used for connecting the motor. For more information, please refer to chapter 8, ”Connection Techniques”.

8. Output Shaft

Not applicable (due to the hollow shaft)

9. Holding Brake

Not available.

10. Frame shape

The standard design is frame shape B05 for flanged mounting.

11. Bearings

The motor bearing consists of cylindrical roller bearings (ID letter “C”) with permanent lubrication. The bearings can be re-lubricated via two connectors on the housing top.

12. Vibration Severity Level

MAL motors are dynamically balanced according to the requirements of DIN ISO 2373; the default level is "R".

13. Other Designs

No option available.

8.2 Power Connector

Operation of a MAL motor requires the following connections.

The power connector is implemented by an INS0480 flange socket on the motor.

Depending on the motor type, a motor blower is connected either with 2 or with 3 phases to the power supply via blower cables and a motor protection switch (example: 3 phases in Fig. 8-1). The blower unit is working independently of the drive device.

Two temperature sensors (KTY84-130) are permanently installed in the motor winding, only one of which may be connected. The wires for connecting the sensor are coming out of the flange socket. If one of the sensors fails, the spare sensor can still be used.

MAL_Power_Plug.EPS

(1): INS0480 flange socket on the motor (2): INS481 coupling on the power cable

Fig. 8-2: Flange socket for power connection to Rexroth MAL motors

Please pay attention to the following when selecting cable connections:

• The motor is always equipped with a flange socket with bayonet lock and the connection cable with a coupling with bayonet lock.

• The flange socket on the motor side and the coupling on the cable side are connected to each other and screwed on. They are therefore structured as a mirror image, i.e.

with different poles.

• The mechanical codings of the flange socket and the coupling must be compatible.

• The design of the power cable also depends on the drive device used.

8.3 Blower Connection

The motor blower is connected to the power supply system via a cable and a motor protecting switch (Fig. 8-1) and is working independently of the control unit.

Note:

• To establish the connection, the blower plug must be opened and closed.

• The electric connection may be established by skilled personnel only. Please observe the safety notes.

• The tightness of the plug housing must not be reduced.

• The machine manufacturer selects the motor protecting switch and the electrical protection. Please observe the regulations in the country of installation.

• The plug for connecting the motor blower is included in the scope of delivery. The cables and the motor protecting switch for the blower are not included in the scope of delivery from Bosch Rexroth.

8-4

8.4 Temperature Sensor

Two temperature sensors (KTY84-130) are permanently installed in the motor winding of MAL motors, only one of which may be connected (Fig.

8-1). The wires for connecting the sensors are coming out of the flange socket. If one of the sensors fails, the spare sensor can still be used. The polarity within a pair of wires is not relevant for the functioning of the temperature sensor.

The pair of wires of the spare sensor lies electrically insulated in the flange socket housing. In order to be able to connect the spare sensor, the housing must be opened.

For additional information on temperature sensors, please refer to section 9.10 ”Motor Temperature Monitoring Circuit”.

Note:

• The signal lines of the sensors are conducted to the controller via the motor power cable (Fig. 8-1).

• Ensure correct polarity when using the sensor for temperature measurement externally (see Fig. 9-10).

• Only one sensor is connected and evaluated. The function of the spare sensor cannot be guaranteed.

8.5 Grease Connector

On their top, MAL motors are provided with two screwed connectors for re-lubricating the motor bearings.

⇒ Only use flexible plug-in plastic tubes and fittings with an appropriate cross-section.

⇒ Avoid any over-lubrication of the motor bearings.

9.2 Air Humidity

Climatic environmental conditions are defined in different classes according to DIN EN 60721-3-3 (1995), Table 1. They are based on observations made over long periods of time throughout the world and take into account all supply parameters that might have an effect, such as the air temperature and humidity.

Based on this table, Rexroth recommends class 3K4 for continuous use of the motors.

This class is excerpted in the following table.

Environmental factor Unit Class 3K4

Low air temperature °C +5 ¹)

9.3 Vibration and Shock

Vibration

Sine-shaped vibrations occur in stationary use; depending on their intensity, they have different effects on the robustness of the motors.

The robustness of the overall system is determined by the weakest component.

According to DIN EN 60721-3-3 and DIN EN 60068-2-6, the following values are approved for Rexroth motors:

Direction Amplitude 0 – 55 Hz

Acceleration 55 – 2000Hz

axial 0.3 mm 1 m/s²

radial 0.75 mm 30 m/s²

Fig. 9-3: Maximum values for sine-shaped vibrations

Shock

The shock load of the motors is indicated by specifying the maximum permitted acceleration in non-stationary use, such as during transport.

Damage to functions is prevented by maintaining the limit values specified.

According to DIN EN 60721-3-3 (1995), the values for MAL motors are as follows:

Motor frame size axial radial

MAL130E 10 m/s² 150 m/s²

Fig. 9-4: Shock stress

Note: Please also observe the specifications in Chapter 10.4 regarding transport and storage.

The construction and effectiveness of shock-absorbing or shock- decoupling attachments depends on the application and must be tested using measurements. This does not lie within the area of responsibility of the motor manufacturer. Modifications of the motor construction result in nullification of the warranty.

9.4 Compatibility with Foreign Material

All Rexroth control and drive devices are developed and tested according to the state-of-the-art.

However, as it is impossible to observe the permanent new development of all materials which may come into contact with our controllers and drive devices (e.g. lubricants for machine tools), we cannot generally exclude any reaction with the materials used in our systems.

For this reason, you will have to carry out a test on compatibility among new lubricants, detergents, etc. and our housing and device materials.

9.5 Degree of Protection

The degree of protection is defined by the abbreviation IP (International Protection) and two reference numbers specifying the degree of protection. The first reference number describes the degree of protection against contact and penetration of foreign bodies; the second reference number describes the degree of protection against the ingress of water.

Motor area Degree of

Protection

Note

Motor IP54

Power and fan connectors IP65

9.7 Transport Protection / Mounting Tool

When delivered ex factory, MAL motors are provided with a transport protection in the form of a securing pin. This securing pin provides

• protection of the rotor during transport,

• a mounting tool for attaching the motor.

Sicherungsstift.EPS

Fig. 9-7: Securing pin on the MAL motor

As transport protection, the securing pin ensures that the rotor remains in its intended axial position (central position) until assembly and cannot be damaged during transport. It also prevents any rotary movements of the rotor.

Note: Please remove the securing pin only after you have mounted the motor, in order to prevent the motor from being damaged from the very start. After having removed the securing pin, please close the hole with a closing screw or an appropriate safety cap. Please also note the information on mounting the rotor in Chapter 11.2 “Motor Attachment”.
