Setting range: 0 – 150% of the nominal motor data I

The factory setting for the current limitation is set to 150% I
N
of the matching motor.
The internal current limitation is based on the apparent current. In the operating
modes "V/f" and "VFC" without speed control, the current limit is automatically re-
duced in field weakening mode above the frequency of 1.15 × f
base
. This implements
stall protection for the connected motor. The current limit effective in the field weaken-
ing range is calculated using the following formula:

The parameter is only effective in "VFC and "V/f" operating modes. The function is
only useful for single motor operation.
Setting range: ON/OFF
When the parameter is activated, the device automatically adjusts the parameter
P322/P332 IxR adjustment 1/2  with every enable and saves the value. The device
thereby determines a basic setting that is adequate for a great number of drive applic-
ations. The connected motor is calibrated in the last 20 ms of the premagnetization
phase, except if:
• the parameter is deactivated
• the operating modes "VFC&Group" or "VFC&flying start function" are set
• the pre-magnetization time (→2205) has been reduced by more than 30ms in
relation to the proposed value.
• in the operating mode "VFC n-control," the parameter P730/P733 brake function
1/2 (→2219) is deactivated.
In such cases, the set IxR value is used for calculating the winding resistance.
