Noise generates because of thedifferent encoder cable specification.3. Noise generates because encodercable is long.4. Encoder cable is bundled withlarge-sized current cable, or runsclose to it.5. FG fluctuates with the influencesfrom the welder with the motor.6. Excessive vibration impact on theencoder.7. Servo pack is broken.8. Encoder is broken.Encoder parameter error1. Servo pack is broken.2. Encoder is broken.Multi-limit mis-compare1. User constant for servo pack iswrong.2. The setup of encoder multi turn limitvalue is wrong.3. Encoder is broken.D e t a i l sC o u n t e r m e a s u r e s1. Replace the servo pack.2. Replace the motor.No communication can be made between the servopack and the encoder.1. Correct the encoder wiring.2. Use the specified cable.3. The maximum wiring distance is 20m.4. Remove serge-applied force from the encodercable.5. Route the grounding cable from machines toprevent the current branch to FG on PG.6. Reduce the machine vibration or check the motorinstallation.7. Servo pack is broken.8. Encoder is broken.Encoder parameter is incorrect.1. Replace the servo pack.2. Replace the motor.Encoder parameter error1. Check PRM561.2. Re-setup the gear ratio of PRM011.3.
