Setting sequence
-
Drives with matching 4 pole standard motors 230/400 V in star connection do not
need to be adapted. After having started the drive, the controller itself detects all
further motor data.
-
The following drives can be optimized by entering the nameplate data ”rated motor
current” and ”cos
j
” under C088 or C091:
- Motor one power class smaller than the motor assigned to the controller.
- Motor one or two power classes smaller than the motor assigned to the controller.
- Drives with 2, 6, 8, 10 and 12 pole standard motors.
- Drives with special motors.
-
With the slip compensation C021, you can optimize the ”sensorless speed control”
for your application.
