Current Regulator Loop
Settings
Current loop bandwidth is set differently based on the selected motor type.
Table 189 - Current Regulator Loop Settings
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.

1000Rotary interior permanent magnet
Linear permanent magnet
Rotary induction 400
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.
