Siemens 300510 - Axis drive error on actual current measurement zero balancing
This alarm indicates a hardware fault in the drive's current measurement system during zero balancing calibration. This is typically caused by faulty current sensors, drive module issues, or electrical interference, not program errors.

Siemens 300510 - Axis drive error on actual current measurement zero balancing
Axis drive error on actual current measurement zero balancing
The value of the actual current exceeded the maximum permissible limits during current zero balancing (performed on every pulse disable). For example, the synchronous motor is rotating at a small intermediate circuit voltage and current is flowing across the free-wheeling diodes in the intermediate circuit Control reaction: NC not ready. The NC switches to follow-up mode. Channel not ready. NC Start disable in this channel. Interface signals are set. Alarm display. NC Stop on alarm. Channel not ready.
Root Cause Summary
This alarm indicates a hardware fault in the drive's current measurement system during zero balancing calibration. This is typically caused by faulty current sensors, drive module issues, or electrical interference, not program errors.
Safety
- Drive/power/encoder circuit: hazardous voltages may remain in the DC link after power-off. Lock out / tag out, wait for discharge per the drive documentation, and use qualified personnel only.
Causes and Fixes
- 1
LOCKOUT/TAGOUT - Isolate power
Follow proper LOTO procedures before any electrical inspection.
- 2
Visual inspection
Check current sensor connections and wiring for damage, corrosion, or loose connections.
- 3
Contact qualified technician
Current sensor replacement requires specialized knowledge and calibration tools.
Call a technician if:
- ·Immediately - this is a drive hardware fault requiring specialized diagnosis
- ·Do not attempt drive module repairs without proper training
Prevention
- Validate programs using simulation before execution
- Ensure G-code matches the control’s capabilities
Common Mistakes
- Overlooking the specific block number in the alarm
- Failing to check subprograms for errors
