Appendix F Motor Control Feature Support
Current Regulator Loop
Settings
Current loop bandwidth is set differently based on the selected motor type.
Motor Category From the Motor category you can enter motor nameplate or datasheet values
(phase-to-phase parameters) for rotary induction motors.
In this example, the Motor category>Nameplate / Datasheet parameters, were
taken from a typical motor performance datasheet. Max Speed and Peak
Current values are typically application dependent.
Figure 224 - Motor Nameplate / Datasheet Example
See Figure 225 for motor manufacturer performance data sheet example.

IMPORTANT
The Logix Designer application does not perform calculations when
the Torque/Current Loop Bandwidth attribute is updated. This
bandwidth affects many other gains and limits. Changing, (lowering)
the torque loop bandwidth without updating all the dependent
attributes can result in drive/motor instability.
