- Drives with matching four-pole standard motors need not be adapted. The data are save in the
factory setting. After having started the drive, the controller itself detects all further motor data.
- Drives with non matching motors must be optimised. Non-matching motors have the following
features.
- Rated motor power > 1.4 k rated inverter power
- Rated motor power < 0.6 k rated inverter power
- Operation with 2, 6, 8, 10 and 12-pole standard motors
- Operation with special motors
The drive can be optimised by entering motor data under C088/C091.
- The control mode C014 = -4- should only be used with the slip compensation. The ”sensorless
speed control” is thus optimised for the process.
- The idle current of the motor (magnetising current) must not exceed the rated current of the
controller.
- The power code of the connected motor should not be more the two classes lower than the one
of the motor assigned to the controller.
Important The change from V/f-characteristic control to motor-current control should only be carried out when
the controller is inhibited.
Special features
821X/822X/824X Control mode motor-current control C014 = -4-
- Motor-current control (factory setting) is not possible if
- drives with different loads are connected to an inverter,
- drives with different rated powers are connected to an inverter,
- you use motor chokes, motor filters, sine filters or sine-interference suppression filters.
- With very small friction values, a phase offset of up to 180 occurs at the motor shaft when
enabling the controller.

- High inertias result in a reduced acceleration of the drive.
- This behaviour can be avoided by changing the parameter sets (e.g. acceleration with
C014 = -2-).
