Current loop bandwidth is set differently based on the selected motor type.

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.
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.
