 Tip!
For magnetising the motor, consider a sufficient time from the controller enable to the
start of the speed ramp function generator.
• The bigger the motor the longer the time required for magnetisation. A motor with a
power of 90 kW requires up to 2 seconds.

If the load adjustment is too high, the motor current may increase in idle state and the
motor may overheat!

Subindex 1: VFC: Load adjustment - direction of rotation
Adaptation of the characteristic depending on the load in the case of CW and CCW rotation
Selection list (Lenze setting printed in bold) Info
0 Passive load (e.g. friction) The motor operates in motor mode in both directions.
1 Active load, CCW (e.g. hoist) Application example: Hoist without counterweight
2 Active load, CW (e.g. hoist) Application example: Dancer-controlled unwinder

Subindex 2: VFC: Load adjustment - value
Load adjustment in [%] proportionally to the rated torque, in order to obtain a correspondingly "rigid" drive
behaviour even after the starting action.
• When starting torque = rated torque, a load adjustment of 50 % is suitable for most applications.
