Identifying
motor data 0 0 Ready Only when the motor is cold!
1. Inhibit controller, wait until
drive is at standstill
2. Enter the correct values from
the motor nameplate in C0087,
C0088, C0089, C0090, C0091
3. Set C0148 = 1, confirm with
v
4. Enable controller:
The identification
– starts,
c goes out
– the motor "whistles" faintly
but it does not rotate!
– takes approx. 30 s
– is completed when
c is lit
again
5. Inhibit controller

1 Start identification
l V/f rated frequency (C0015), slip
compensation (C0021) and motor
stator inductance (C0092) are
calculated and saved
l The motor stator resistance (C0084)
= total resistance of the motor cable
and motor is measured and saved
Setting of torque control
Use C0014 = 5 to set the operating mode "sensorless torque control".
Linking setpoint and selecting speed limitation
Link an external setpoint source with the torque setpoint via C0412/6. (
¶ 328)
Select the type of speed limitation. The speed is limited via setpoint 1 or the maximum
frequency:
ƒ Setpoint 1, if C0412/1 is linked with a setpoint source.
ƒ Maximum frequency, if C0412/1 is not assigned.
