5.5.2.2 Motor stator resistance

For the adjustment of the motor stator resistance, first the motor current at standstill (without load

of the motor) is compared to the motor magnetising current. Afterwards the setting of the motor

stator resistance is changed step by step until the motor current stably reaches the motor

magnetising current.

 How to adjust the motor stator resistance:

1. Select setpoint speed 0 rpm or activate quick stop.

2. Enable controller.

3. Compare the motor current displayed in C00054

with the motor magnetising current

displayed in C00092

.

4. Inhibit controller.

5. If motor current > motor magnetising current:

• Reduce the motor stator resistance stepwise in C00084

.

If motor current < motor magnetising current:

• Increase the motor stator resistance stepwise in C00084

.

6. Repeat steps 2 ... 5 until the following applies: Motor current ≈ motor magnetising current.

7. Save parameter set (C00002

= "11: Save start parameters").
