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

Noise If the Servomotor cable and the
external encoder cable are bundled
together, separate them. Connect the
shield to FG.
