=
open-loop
(U/f-curve)

=
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!

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