W Control; Motor Data - WEG CFW700 Programming And Troubleshooting Manual

10.1 V V W CONTROL
Only three parameters are related to this function: P0139, P0202 and P0397.
However, since the parameters P0139 and P0202 were already presented in the
parameter P0397 will be described next.
P0397 – Slip Compensation During Regeneration
Adjustable 0 = Off
Range: 1 = On
Properties: cfg and V V W
Access groups
via HMI:
Description:
It enables or disables the slip compensation during the regeneration in the V V W control mode. Refer to the
parameter P0138 in the section 9.1 - V/f

10.2 MOTOR DATA

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
11.7 - Motor Data.
P0398 – Motor Service Factor
Refer to the section 11.7 - Motor
P0399 – Motor Rated Efficiency
Adjustable
50.0 to 99.9 %
Range:
Properties:
cfg and V V W

MOTOR
via HMI:
Description:
It sets the motor rated efficiency.
This parameter is important for the V V W control precise operation. The inaccurate setting implies in incorrect
calculation of the slip compensation and consequently an imprecise speed control.
