APC ALARM: PULSE ERROR

What does SV0305 mean?

A pulse error occurred with the absolute-position detector, preventing the system from obtaining the correct machine position. This issue is typically caused by a defect in the absolute-position detector or its connecting cable.

• APC encoder pulse generation is inconsistent or faulty.
• Signal degradation of the encoder's pulse output.
• Incorrect pulse counting by the CNC.
• Mechanical issues affecting the encoder's disc rotation.

Click steps to track your progress.

1. 1

   Measure APC encoder pulse output (e.g., A, B signals) for correct waveform and frequency.

2. 2

   Inspect encoder mounting for any mechanical play or vibration.

3. 3

   Verify pulse counting parameters in the CNC.

4. 4

   Test APC encoder with a known good reference if possible.
