Other functions
Inhibit direction
Under PNU b035, you can specify whether clockwise or
anticlockwise motor operation is permitted.
Starting behaviour
With the two parameters PNU b036 and b082, you can specify the
voltage ramp and the frequency for starting the motor.
Voltage ramp
If the overcurrent trip is triggered at an increased starting
frequency, you can reduce the starting current and the torque with
PNU b036.
Starting frequency
Under PNU b082, you can set the frequency at which the motor is
to start.
