Siemens 840D 101164 - MDx132 MOTOR_NOMINAL_VOLTAGE <= 0
Alarm 101164 indicates that the motor nominal voltage parameter (MD1132) has been configured with an invalid value of zero or less. This is a critical motor data configuration error that prevents proper motor control and must be corrected before operation can continue.

Root Cause Summary
Alarm 101164 indicates that the motor nominal voltage parameter (MD1132) has been configured with an invalid value of zero or less. This is a critical motor data configuration error that prevents proper motor control and must be corrected before operation can continue.
Safety
- Refer to Siemens documentation
- Ensure qualified technician performs repairs
Causes and Fixes
- 1
Access drive parameter settings via HMI: Navigate to Commissioning > Drive > Motor data for the affected axis.
- 2
Locate MD1132 MOTOR_NOMINAL_VOLTAGE parameter and verify current value shows 0 or negative number.
- 3
Check motor nameplate on physical motor and record the nominal voltage (typically 230V, 400V, 460V, etc.).
Ensure motor power is locked out before accessing motor nameplate if necessary.
- 4
Enter correct nominal voltage value into MD1132, save parameters, perform power-on reset (NCK reset), and clear alarm.
