LDAL alarm (Pulsecoder LED Broken)

What does SRVO-074 mean?

This alarm (Group:i Axis:j) signifies that the LED within the Pulsecoder is broken or faulty. This prevents the Pulsecoder from generating proper position feedback, directly affecting axis control and potentially leading to inaccurate positioning or uncontrolled motion.

• Pulsecoder LED (LDAL - LED Abnormality) has failed or is not emitting light.
• Optical feedback path within the pulsecoder is obstructed or broken.
• Dirty or damaged encoder disk or sensing surface.
• Faulty LED driver circuit within the pulsecoder.
• Pulsecoder internal diagnostics detecting LED failure.
