DESCRIPTION OF PARAMETERS
2.1 MOTOR
PARAMETERS
2.1.1
Nominal voltage of the motor
Find this value U
n
on the rating plate of the motor. This parameter sets the voltage at
the field weakening point (parameter 2.5.5) to 100% x U
nmotor
.
2.1.2
Nominal frequency of the motor
Find this value f
n
on the rating plate of the motor. This parameter sets the field
weakening point (
) to the same value.
2.1.3
Nominal speed of the motor
Find this value n
n
on the rating plate of the motor.
2.1.4
Nominal current of the motor
Find this value I
n
on the rating plate of the motor.
2.1.5
Motor cos phi
Find this value “cos phi” on the rating plate of the motor.
2.1.6 Current
limit
This parameter determines the maximum motor current from the frequency converter.
To avoid motor overload, set this parameter according to the rated current of the
motor. The current limit is equal to the rated converter current (I
L
) by default.
