What does 15 mean?
The motor stall protection has tripped, indicating that the motor has either stopped or is operating at a very low speed while a run command is active and under mechanical load. This typically suggests an excessive mechanical load or a mechanical obstruction preventing motor rotation.
Common Causes
- Motor shaft mechanically locked or jammed.
- Excessive load torque preventing rotation (P0200).
- Incorrect motor parameters configured (P0201).
