4. Check the number of Motor Modules that you have set in the topology.
5. To carry out further checks, double-click ".../Drives/Drive_1 > Configuration" in the project
Operating a parallel connection in master/slave mode
Motor Modules connected in parallel can also be operated in master/slave mode.
1. To do this, use parameter p1330 to transfer the input of the V/f characteristic to the next

The braking resistors must be dimensioned for each Motor Module according to the table
of resistances above.

A dialog opens allowing you to check the current configuration. The "Current power unit
operating values" button lists the Motor Modules according to component number. During
operation, they show the current electrical values.
