7-6 Using Multi-Drive Mode
The example ladder logic program demonstrates using Multi-Drive
mode with five drives. See Figure 7.2
for a system layout diagram.
Function of the Example Program
The example program provided is for the ControlLogix, but other
controllers can also be used. This example program enables you to:
View status information from the drives such as Ready, Fault, At
Speed, and Feedback.
Control the drives using various Logic Command bits (Stop, Start,
etc.) and Reference.
Perform a single parameter read and write for each drive. The
example uses drive Parameter 39 - [Accel Time] for both so you can
see (read) the change after a write is performed.
Adapter Settings for the Example Program
The Operating Mode Switch (SW1) on the adapter is set to the
Multi-Drive operation position. See Chapter 2, Setting Operating
Mode and Web Pages Switches.
The following adapter parameters are set:
