SRVO-085

SRVO-085: RCAL alarm (track encoder rotation counter)

Line-tracking mirror of SRVO-063: the conveyor encoder's rotation counter miscounted - grounding/noise first, encoder second.

What it means

Line-tracking mirror of SRVO-063: the conveyor encoder's rotation counter miscounted - grounding/noise first, encoder second.

Common causes

Ranked by what technicians most often find, most likely first.

  1. Weak grounding at the encoder flange letting noise corrupt the count.
  2. Phantom alongside SRVO-090/091/092.
  3. Failed encoder.

How to fix it

  1. Check the 090/091/092 trio first.
  2. Reinforce the encoder flange ground.
  3. Replace the motor/encoder if it persists; recovery is PULSE RESET then power cycle.
