Using Multi-Drive Mode

Important: Due to PLC-5 controller limitations, explicit messaging

cannot be performed in Multi-Drive mode.

This example ladder logic program demonstrates using Multi-Drive
mode with five drives. See

Figure 7.2

or

Figure 7.3

for a system layout

diagram.

Function of the Example Program

This example program enables you to:

• View status information from the drives such as Ready, Faulted, At

Speed, and Feedback.

• Control the drives using various Logic Command bits (Stop, Start,

etc.) and Reference.

Main Routine

The Main Routine reads the network Input Image from the scanner,
initiates Drive 0 through Drive 4 control subroutines (U:3 through U:7
files), and writes the network Output Image to the scanner. See

Figure 7.17

.
