Question
What is the cause of the E23 error in an
R88D-HT10 Servo Driver?
Answer
The 23 error occurs when there is an open
phase in the main circuit. An error is detected when a low voltage was
detected in the main circuit's input section and lasted longer than 50 ms.
The likely causes of the error are that the main voltage power supply is
not being input or there is an open phase in the main circuit. In general,
this error is caused by a problem to the power supply input section. Check
the main circuit power supply wiring.
