Assumed cause Remedy Prevention
There is insufficient power supply
voltage for the encoder.
Provide the required encoder power
supply voltage of 5 VDC ±5% (4.75 to
5.25 V).
Provide the required encoder power
supply voltage of 5 VDC ±5% (4.75 to

Noise is entering on the encoder line. If the Servomotor cable and the
encoder cable are bundled together,
separate them. Connect the shield to
FG.
