Current Regulator [91] - WEG CFW-11 Programming Manual

P0166 – Speed Regulator Differential Gain
Adjustable 0.00 to 7.99
Range:
Properties: PM and Vector
Access groups 01 PARAMETER GROUPS
via HMI:
Description:
The differential action helps minimize the motor speed variations generated by sudden load changes. Refer to the
Figure 11.1 on page 11-2

11.8.2 Current Regulator [91]

The parameters related to the CFW-11 current regulator are presented in this group.
P0167 – Current Regulator Proportional Gain
Adjustable 0.00 to 1.99
Range:
P0168 – Current Regulator Integral Gain
Adjustable 0.000 to 1.999
Range:
Properties: Vector
Access groups 01 PARAMETER GROUPS
via HMI:
Description:
Parameters P0167 and P0168 are adjusted automatically as a function of the parameters P0411 and P0409,
respectively.
NOTE!
Normally, those parameters do not require further adjustment. However, when the P0296 setting
is higher than the P0400 setting, or when the bus DC voltage is controlled by an AFE (Active Front
End), then current instability may occur.
