¿Qué significa SRVO-075 ?

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.

Causas comunes

  • Initial pulse signal from the pulsecoder has not been established within the expected timeframe.
  • Pulsecoder not providing a valid position reference signal at startup.
  • Encoder initialization error during servo system power-up.
  • Faulty pulsecoder unable to generate initial homing or reference pulses.
  • Incorrect homing procedure or missing reference marker detection.
