VVW Control
CFW700 | 10-3
10.1 VVW 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 section 9.1 - V/f Control , only the
parameter P0397 will be described next.
P0397 – Slip Compensation During Regeneration
Adjustable
Range:
0 = Off
1 = On
Factory
Setting:
1
Properties: cfg and VVW
Access 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 - V/f Control , for more details on the slip compensation.
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 section
11.7 - Motor Data .
P0398 – Motor Service Factor
Refer to the section 11.7 - Motor Data , for more information.
P0399 – Motor Rated Efficiency
Adjustable
Range:
50.0 to 99.9 % Factory
Setting:
67.0 %
Properties: cfg and VVW
Access groups
via HMI:
MOTOR
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.
