AL.024 Encoder initial magnetic field error – Delta servo troubleshooting

Name	Description	ALM	WRN	SRV ON	Clear Way
AL.024	The magnetic field of the encoder U, V, W signal is in error.	⊗		NO	Re-power on

Causes	Checking Method	Actions
The initial magnetic field of the encoder is in error (Signal, U, V, W of the encoder magnetic field is in error.)	Check if the servo motor is properly grounded. Check if the encoder cable separates from the power supply or the high-current circuit to avoid the interference. Check if the shielding cables are used in the wiring of the encoder	If issue persists, please send the drive back to the distributors or contact with Delta.
