CP.17 Load motor dependent parameter
The basic settings of the inverter correspond to the size of the unit and the respective motor (see 3.3 „Factory
Settings"). If the motor data in CP.11...16 are changed, then CP.17 must be activated once. This re-adjusts the
current controller, torque curve and torque limit. With this, the torque limit is set at the value, that is maximally
possible in the speed range (depending on inverter rated current), but not above the rated motor torque x 3.

Setting Description
see 3.3 Adjustment of the rated motor power according to the name plate. The factory
setting depends on the unit size ( see 3.3 „Factory Settings").
Setting Description
x Pre-adjustment of the motor-dependent control-parameters.
The voltage class of the inverter is taken as input voltage.
Pre-adjustment of the motor-dependent control-parameters.
The measured DC-link voltage divided by √2 measured at switch on is taken
as input voltage. Thus the frequency inverter can be adapted to the actually
available mains voltage (e.g. USA with 460 V).
When control release is active the adjustment was not completed. „nco" appears in the
display.
Setting Description
2 % In the lower speed range a large part of the motor voltage decreases on the
stator resistance. So that the breakdown torque of the motor remains nearly
constant in the controlled operation over the entire speed range, the voltage
drop can be compensated by the Boost. During regulated operation (CP.10
= 4 or 5) this parameter has no function.
Adjustment:
• Determine the rate of utilization in no-load operation with rated speed
• Preset about 300 rpm and adjust the boost, so that about the same rate of
utilization is reached as with the rated speed.
When the motor, during continuous operation, drives with low speed and too high voltage
it can lead to an overheating of the motor.
