Secondary Motor Control Chapter 4
One Drive, One Motor, and Multi-Motor Control
You can use secondary motor control when one PowerFlex 755T drive is used to
switch from controlling one motor to controlling a multi-motor system. For this
example, the PowerFlex 755T drive is configured to switch between controlling
one motor in induction flux vector mode and controlling a multi-motor system
in induction VHz mode. Induction Flux Vector is configured in the Primary
Motor Control profile, and Induction VHz is configured in the Secondary
Motor Control profile.
The drive is configured to switch between the primary and secondary motor
control profiles that are based on which contactor is closed and electrically
connected to the specified motor.
