Siemens 840D 101163 - MDx130 MOTOR_NOMINAL_POWER <= 0
Alarm 101163 indicates that the motor nominal power parameter (MD1130) in the axis or spindle machine data is set to zero or a negative value. This is a configuration error that prevents the drive system from calculating proper motor control parameters, as the control requires a valid positive power rating to configure torque limits, thermal monitoring, and power stage settings.

Root Cause Summary
Alarm 101163 indicates that the motor nominal power parameter (MD1130) in the axis or spindle machine data is set to zero or a negative value. This is a configuration error that prevents the drive system from calculating proper motor control parameters, as the control requires a valid positive power rating to configure torque limits, thermal monitoring, and power stage settings.
Safety
- Refer to Siemens documentation
- Ensure qualified technician performs repairs
Causes and Fixes
- 1
Access HMI Service mode and navigate to the affected axis/spindle commissioning data.
- 2
Locate MD1130 MOTOR_NOMINAL_POWER for the affected drive axis and verify current value is 0 or negative.
- 3
Enter the correct motor nominal power in watts from the motor nameplate (e.g., 6000 for a 6kW motor).
Ensure value matches the actual motor installed. Incorrect power rating will cause improper current limiting and potential motor damage.
- 4
Perform NCK reset (POWER ON) and verify alarm clears and drive enables properly.
