–starts,
c gets out
– the motor makes a high-pitched tone,
but does not rotate!
– takes approx. 30 s
– is completed when

5. Controller inhibit
Use C0014 = 5 to set the operating mode ”sensorless torque control”.
Link an external setpoint source with the torque setpoint via C0412/6.
(¶ 10.12-1)
Select the type of speed limitation. The speed is limited via setpoint 1 or the
maximum frequency:
l Setpoint 1, if C0412/1 is linked with a setpoint source.
l Maximum frequency, if C0412/1 is not assigned.
You must enter the motor data of the motor nameplate:
l Rated motor speed (C0087)
l Rated motor current (C0088)
l Rated motor frequency (C0089)
l Rated motor voltage (C0090)
l Motor cos ϕ (C0091)
Carry out the motor parameter identification. (
^ 10.9-1 )
V/f-rated frequency (C0015), slip compensation (C0021) and motor stator
inductivity (C0092)are calculated and saved. The total resistance of motor cable
and motor is measured and saved as motor stator resistance (C0084).
