Operation
Chapter Section Page Date
In CP.32 you can select whether the inverter operates open-loop or closed loop.
Adjustment Range: 0…1
Resolution: 1
Factory setting: 0
Customer setting: ________
0 = open-loop (U/f-curve)
1 = closed-loop (field-oriented control)
During open-loop operation the torque limits, levels and displays do not have a function.
All parameters, that access these values, either do not have a function or have a
restricted function. This is described in the individual parameters.
Speed Regulation on/off
Boost
The voltage increase for the lower speed range is adjusted with the boost, which
results in a higher torque in the lower range. During closed-loop operation this
parameter does not have a function!
Adjustment Range: 0…25,5 %
Resolution: 0,1 %
Factory setting: 2 %
Customer setting: ________ %
Caution ! Only switch over when control release is
open ! Torque jumps may occur if not observed.

When the motor is driven during continuous operation at a slow
speed and the voltage is too high, the motor may overheat!
