What is the cause of the E23 error in an R88D-HT10 Servo Driver?
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.
