Description: Induction motors:
Sets the rated motor magnetizing current.
For p0320 = 0.000 the magnetizing current is internally calculated and displayed in r0331.
Synchronous motors:
Sets the rated motor short-circuit current.
Caution: This parameter is automatically preset for motors from the motor list (p0301). When selecting a catalog motor, this
parameter cannot be changed (write protection). Information in p0300 should be carefully observed when removing
write protection.
Note: The magnetizing current p0320 for induction motors is reset when quick commissioning is exited with p3900 > 0.
If, for induction motors, the magnetizing current p0320 is changed outside the commissioning phase (p0010 > 0),
then the magnetizing inductance p0360 is changed so that the EMF r0337 remains constant.
Description: Sets the maximum motor speed.
Dependency: Refer to: p1082
Caution: This parameter is automatically preset for motors from the motor list (p0301). When selecting a catalog motor, this
parameter cannot be changed (write protection). Information in p0300 should be carefully observed when removing
write protection.
Notice: If p0322 is changed during quick commissioning (p0010 = 1), then the maximum speed p1082, which is also asso-
ciated with quick commissioning, is pre-assigned accordingly.
Description: Sets the maximum permissible motor current (e.g. demagnetizing current for synchronous motors).
Caution: This parameter is automatically preset for motors from the motor list (p0301). When selecting a catalog motor, this
parameter cannot be changed (write protection). Information in p0300 should be carefully observed when removing
write protection.
Notice: If p0323 is changed during quick commissioning (p0010 = 1), then the maximum current p0640 is pre-assigned
accordingly.
Note: This parameter is automatically preset for motors from the motor list (p0301).
The parameter has no effect for induction motors.
The parameter has not effect for synchronous motors if a value of 0.0 is entered. The user-selectable current limit is
entered into p0640.
