What does SRVO-096 mean?
This alarm (Track enc:i) indicates that the LED in the Pulsecoder (track encoder) is broken. This prevents the track encoder from generating proper position feedback, leading to loss of position control for the track. The cause and fix are identical to SRVO-074 for robot axes.
Repair Steps
- 1
Replace the Pulsecoder for the affected track encoder.
- 2
Remaster the robot after Pulsecoder replacement to re-establish absolute position.
