Explanation of the parameters
Parameters
32_
Motor adjustment
The
P320 Automatic adjustment function is only of significance for single motor operation. You can use this function for
all motors and control modes. The inverter automatically sets
P322 IxR compensation and P321 Boost with each enable
operation and saves the values. The inverter thereby determines a basic setting which is suitable for many different
drive tasks.
The factory settings of parameters 321 ... 324 depend on the motor.

•
Automatic adjustment
off / OFF
No automatic calibration: The inverter does not calibrate the motor.
on / ON
Automatic calibration: The inverter calibrates the motor every time there
is a change to ENABLE operating status.
321
•
Boost
Setting range 0 ... 100 [%]
Manual setting is normally not necessary. In exceptional cases, manual set-
ting may be necessary to increase the breakaway torque. In this case set to
max. 10 %.
322
•
IxR compensation
Setting range 0 ... 100 [%]
The inverter sets the value automatically when
P320 Automatic adjustment
= ON. Manual alterations to this parameter are reserved for optimization by
specialists.
323
•
Premagnetizing time
Setting range 0 ... 2 [s]
Premagnetization ensures a magnetic field is established in the motor when
you enable the inverter.
324
•
Slip compensation
Setting range 0 ... 500 [rpm]
Slip compensation increases the speed accuracy of the motor. Enter the
rated slip of the connected motor as a manual entry. Do not enter a value
more than 20 % different from the rated slip in order to compensate for fluc-
tuations between various motors.
Slip compensation is configured for a ratio between the moment of inertia of
the load and the moment of inertia of the motor of less than 10. If the ratio is
greater and vibration results, then reduce the slip compensation even down
as far as 0 if necessary.
325
•
No-load-damping
on / ON
off / OFF
No-load damping can lead to an improvement if the no-load characteristic of
the motor is tending towards instability.
No.
