Navigate to HMI Commissioning mode → Drive → Motor Data → Select affected axis motor data set (MD1xx series).

Locate MD118 MOTOR_STANDSTILL_CURRENT parameter and verify current value is 0 or blank.

Enter correct motor standstill current value from motor nameplate or manufacturer datasheet (typically 60-100% of rated motor current for synchronous motors).

Incorrect standstill current values can cause motor overheating or inadequate holding torque

Save motor data, perform NCK reset (Power ON with NCK reset), and execute drive optimization if required.

Check MD362 MOTOR_DATA_SET_ASSIGNMENT for the affected axis to verify which motor data set is assigned.

Verify MD100 MOTOR_TYPE parameter matches the physical motor (2=synchronous motor, 3=linear motor, 1=asynchronous motor).

If motor type is correct, assign the proper motor data set number with complete commissioning data, or run SINUMERIK motor commissioning wizard.

Ensure motor data set matches the actual motor connected to prevent equipment damage

Perform complete motor data commissioning including all required parameters (MD101-MD127 range) and save configuration.

Access HMI → Commissioning → Drive → Motor Commissioning and select the affected axis.

Run the automatic motor commissioning wizard or manually enter all motor nameplate data including rated current, standstill current, torque constant, and electrical parameters.

For synchronous motors, set MD118 to 60-100% of MD102 (MOTOR_RATED_CURRENT) based on motor manufacturer specification.

Verify exact standstill current specification from motor documentation

Execute drive optimization routine (measuring cycle for motor/encoder) and verify alarm clears after NCK reset.
