Fanuc · R-30iB Mate + Mate Plus Robot

What does SRVO-075 mean?

This alarm (G:i A:j) indicates that the absolute position of the Pulsecoder cannot be established. This typically occurs during startup or after a power cycle if the encoder's absolute position data is lost or corrupted, preventing the robot from determining its current joint angles.

Repair Steps

  1. 1

    Reset the alarm condition.

  2. 2

    Jog the affected axis until the alarm no longer occurs, allowing the Pulsecoder to re-establish its position.
