Spindle Amplifier Current Overload

Was bedeutet SP0022 ?

The spindle amplifier is experiencing an overcurrent condition. This can be caused by excessive load on the motor, a short circuit, or incorrect current limits.

• Excessive mechanical load on the spindle motor.
• Short circuit within the spindle motor windings.
• Amplifier output transistors have failed.
• Incorrect motor tuning parameters (e.g., P5-XX related to current limits).

1. 1

   Measure spindle motor current during operation using P5-04.

2. 2

   Inspect motor for bearing issues or mechanical binding.

3. 3

   Perform motor winding resistance test between phases (U, V, W).

4. 4

   Review and adjust current limit parameters (e.g., P5-02, P5-03) if set too low.
