In CP .32 you can select whether the inverter operates open-loop or closed loop.
Adjustment Range:

Factory setting:
Customer setting:
0 = open-loop
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.
Caution !
open !
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!

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