Edit Screen

Use the Program Edit screen to enter the complete executable program.

Also use this screen to edit or review an existing program.

Edit Screen

E - indicates edit screen

0096 block number, 00002999 is user selectable for edit and review -automatically increments to next higher number during programming BCE - command mneumonic

0200 02 1 - data for the block command

When first scrolling to this screen, a flashing cursor appears in the home position (first digit of the block number). As with other display screens which include a cursor, press the left or right arrow keys to move the cursor within the screen. Also, press the CR key to move the cursor to the home position. Press CR again to position the cursor to the first position of the previous field. Continue pressing the CR key until the cursor is in home position or over the left digit of the block number, before using the up/down arrow keys to scroll to different display screens.

To select different program blocks of information to display (for review or edit), press the right/left arrow keys to position the cursor over the first digit of the block number and type over the existing block number.

Command and data for this selected block will then appear. To scroll through the block numbers, press the CR key to locate the cursor in the top line, then use the + or - key to scroll through the blocks. The block number will increase or decrease accordingly and display the respective data for each block.

To enter program, start at block "0000" for task 1. Note that task 2 and task 3 programs start at the block number assigned by the user in parameter B006. If block "0000" is not displayed, press the CR key until the cursor is positioned on the first digit of the block number. Type the number "0000" to display that block number.

To enter or change a program command for each block, first press the right arrow key until the cursor moves to the right of the three digit program command mnemonic (i.e. NOP_). Press the up or down arrow keys to increment or decrement through the commands alphabetically.

When the desired command appears on the screen, press the right arrow key. The cursor moves to the beginning of the second line where the data fields appear specifically for the selected command. If this block was not previously programmed with this same command, asterisks (*) appear in the digit positions where data must be entered. After entering and verifying the program block, press the Store key to save the programmed block to memory. The next program block number automatically appears, waiting to be programmed. Continue this process until all lines of user program are done. Note that the program can be edited or added to at a later time.

When changing data from the Edit screen, pressing the CR key before pressing the Store key, will cancel the change and leave the data as previously stored (saved). The display remains at the same block number and the cursor moves to the first position of the previous field. Changing to another block number, display screen, etc. without first pressing the Store key also causes loss of a change to a block's data.

Chapter 5 provides the information on commands required for creating the user executable program.

3 Functional Description of DEA 4 I/O Connections

The DLC motion control system is designed to function harmoniously within the machine builder's equipment design. The DEA 4 Input/Output card which plugs into the U2 slot of Indramat's Digital Drives. The DEA 4 provides several input / output signals to handshake between the DLC control and the machine builder's equipment. This chapter describes the functional operation of the interfacing inputs and outputs of the DEA 4 with DLC control card.

The first sections of this chapter describe the various interface functions in terms of the inputs / outputs involved with each. This includes the pre-defined I/O connections of the DLC/DEA 4, as well as certain functions which the user can select through parameter or programming, using auxiliary I/O connections. Certain auxiliary output functions are set in firmware, as described in Chapter 5 for user programming.

This first section is followed by an individual description of each pre-defined I/O signal, including name, pin assignments, and functional description. The designer utilizes these signals as necessary to implement the DLC for the application, including the design of the system control panel.

3.1 Signal Definitions

The states of the input and output signals described in this manual are:

• High = +24 Vdc

• Low = 0 Vdc

A signal line is described as "active high" when its associated action is initiated by a high (+24 Vdc) signal level. It is described as "active low"

when its function is initiated by a low signal (0 volts). Active low signals are shown in this manual (when specifically referred to as a signal) with a bar (line) over the signal name, as an example,

'OGTIGPE[5VQR

signal must be high during normal operation. If it goes low, the DLC initiates the actions required for an emergency stop function.

3.2 Interface Descriptions

The DLC input and output signals provide handshaking to/from the machine builder's equipment. Certain I/O signals should be considered as functional groups of signals, working in concert.

These functions include:

• Operating Mode Selection

• Safety Interlocks

• Normal Operation Signals
