Adjustment of the motor current for zero speed according to the data sheet. The
factory setting depends on the motor.
Adjustment range:
Resolution:
Factory setting:
With the adjusted frequency the inverter reaches in controlled operation a maximal
output voltage. The adjustment of the rated motor frequency is typical in this case.
Note: Motors can overheat when the rated frequency is incorrectly adjusted.
During regulated operation (CP.10 = 4 or 5) this parameter has no function.
Adjustment range:

Factory setting:
The basic settings of the inverter correspond to the size of the unit and the respective
motor (see 4.3.7 "Factory Settings"). If the motor data in CP.11...18 are changed, then
CP.19 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.
CP.19 = 1 : Å Pre-adjustment of the motor-dependent control-parameters.
Å The voltage class of the inverter is taken as input voltage.
CP.19 = 2 : Å Pre-adjustment of the motor-dependent control-parameters.
Å The DC-link voltage / √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.
