MOTOR RATED VOLTAGE
This parameter should be set to the rated (nameplate) voltage of the motor (Volts).
Drive Rating

0…660V
Voltage
Note : The stress on the motor insulation is always dependant on the drive supply voltage.
This also applies in the case where the motor voltage rating is lower than the rating of the
drive and the supply of the drive.

MOTOR RATED CURRENT
This parameter should be set to the rated (nameplate) current of the motor.

MOTOR RATED FREQ
This parameter should be set to the rated (nameplate) frequency of the motor

25…500Hz
Frequency
9908
MOTOR RATED SPEED
This parameter can optionally be set to the rated (nameplate) rpm of the motor. When set to
the default value of zero, all speed related parameters are displayed in Hz, and the slip
compensation for the motor is disabled. Entering the value from the motor nameplate
enables the slip compensation function, and the ACS255 display will now show motor speed
in estimated rpm. All speed related parameters, such as Minimum and Maximum Speed,
Preset Speeds etc. will also be displayed in Rpm.

MOTOR PARAMETER
AUTO-TUNE ENABLE
Drive measures the motor parameters for optimum control and efficiency. Following
completion of the autotune.
0 : DISABLE
