Omron · NJ/NX-series Machine Automation Controller
A communication disconnection was detected between the encoder and the Servo Drive. This indicates a loss of signal, potentially due to cable issues, power problems, or encoder failure, leading to loss of position feedback.
Click steps to track your progress.
Inspect the encoder cable for physical damage, proper connection, and secure termination at both ends.
Measure the power supply voltage to the encoder to ensure it meets specifications.
Implement noise countermeasures on the encoder cable.
Check signal line continuity of the encoder cable.
