Cause and
correction
Assumed cause Remedy Prevention
There is insufficient power supply
voltage for the external encoder.
Provide the required external encoder
power supply voltage of 5 VDC ±5%
(4.75 to 5.25 V).
Provide the required external encoder
power supply voltage of 5 VDC ±5%
(4.75 to 5.25 V).
Noise is entering on the external
encoder connector cable.
If the Servomotor cable and the
external encoder cable are bundled
together, separate them. Connect the
shield to FG.
If the Servomotor cable and the
external encoder cable are bundled
together, separate them. Connect the
shield to FG.
The external encoder failed. If none of the above causes applies,
replace the external encoder.
