SRDY Signal On Prematurely

What does SRVO-022 mean?

The SRDY signal is already ON when the HRDY signal is about to go ON. This means the servo system is indicating that the magnetic contactor is engaged before the host controller has commanded it to do so, suggesting an internal fault in the servo amplifier's control circuit.

• The SRDY (Servo Ready) signal has turned ON prematurely.
• This indicates that the servo drive has signaled readiness before it should have, possibly due to a reset or an unexpected internal state change.
• It suggests that the axis may not be fully initialized or that there is an issue with the system's state management.
• This can lead to unexpected behavior if motion commands are issued before the system is truly ready.
