1.3 Handling methods for alarms/warnings
Check/action method
Decrease the control gain, and then check the repeatability. If the error does
not repeat, use the encoder with a lower gain.
Check if the external conductor of the encoder cable is connected to the
ground plate of the connector.
Refer to "Ground plate connection" in the following manual.
Rotary Servo Motor User's Manual (HK series)
Replace the servo motor.
Check the noise, ambient temperature, and others, and implement appropriate
countermeasures for the cause.
If there is noise, take countermeasures to reduce the noise.
Refer to "Noise reduction techniques" in the following manual.

Check/action method
Replace the servo motor.
Check if the external conductor of the encoder cable is connected to the
ground plate of the connector.
Refer to "Ground plate connection" in the following manual.
Rotary Servo Motor User's Manual (HK series)
Check the noise, ambient temperature, and others, and implement appropriate
