Position Sensor Polarity Setting Incorrect

¿Qué significa SP0021 ?

The polarity setting for the position sensor is incorrect. This can lead to incorrect position feedback and unstable spindle control.

• Position sensor cable wired with reversed polarity.
• Incorrect setting of position sensor type in CNC parameters.
• Faulty position sensor unit.
• Electrical noise interfering with sensor feedback signal.

1. 1

   Verify position sensor wiring according to manufacturer diagram (e.g., A/B phase, Z pulse).

2. 2

   Adjust parameter P4-XX (position sensor type) to match installed sensor.

3. 3

   Measure sensor output signals for correct phase sequence.

4. 4

   Install shielded cabling for position sensor to reduce noise.
