Motor Data [43] - WEG CFW-11 Programming Manual

10.1 VVW CONTROL [25]
The parameter group [25] – VVW Control – contains only 5 parameters related to that function: P0139, P0140,
P0141, P0202 and P0397.
However, since the parameters P0139, P0140, P0141 and P0202 were already presented in the section 9.1,
only the parameter P0397 will be described next.
P0397 – Slip Compensation During Regeneration
Adjustable 0 = Inactive
Range: 1 = Active
Properties: CFG and VVW
Access groups 01 PARAMETER GROUPS
via HMI:
Description:
It enables or disables the slip compensation during the regeneration in the VVW control mode. Refer to the parameter
P0138 in the section 9.1 for more details on the slip compensation.

10.2 MOTOR DATA [43]

The parameters for the used motor data setting are listed in this group. They must be adjusted according to
the motor nameplate data (P0398 to P0406, except P0405) and by means of the Self-Tuning or from data
of the motor data sheet (other parameters).
In this section only the parameters P0399 and P0407 will be presented, the others are presented in the
section 11.7.
P0398 – Motor Service Factor
Refer to the section 11.7 for more information.
P0399 – Motor Rated Efficiency
Adjustable 50.0 to 99.9 %
Range:
Properties: CFG and VVW
Access groups 01 PARAMETER GROUPS
via HMI:
Description:
It sets the motor rated efficiency.
This parameter is important for the VVW control precise operation. The inaccurate setting implies in incorrect
calculation of the slip compensation and consequently an imprecise speed control.
