Parameter setting of the V/f characteristic control
Overview of the relevant parameters
How to parameterise the V/f characteristic:
1. Select the operating mode " V/f characteristic control" with appropriate
2. When using an asynchronous motor which deviates from the standard motor,
having a different rated frequency than 50 Hz (star) / 87 Hz (delta) and a different
number of pole pairs than 2:
• Enter nameplate data of the motor (at least rated speed, rated frequency and
rated voltage)
3. If required, adapt the base frequency of the V/f characteristic
4. If required, rise the V/f characteristic by V
