I've purchased a GSK218MC-H system from you and completed the installation. I had already entered all the parameter settings for the spindle driver (ZJY265-11BM-B5(B3)). Now when i turned it ON, the driver unit shows an error-3 on its display and the spindle motor has not running. I checked the DC power voltage its shows 24 VDC.  Looking forward for your reply.

Please kindly check the input power of spindle motor and driver is normal or not?  it should be 380V/3phase.

Thank you for the reply. I checked the power supply with multimeter. It shows a reading of 406 VAC (both r,s,t & r,t) and it is 3 phase power supply.

can you please help me to figure out what the problem for the error code (Error-3) on spindle driver. Power supply and all was fine. Its 406 VAC/3 phase supply. Looking forward for your reply.

Please try to disconnect the spindle motor.

Connect T with t, Connect R with r.

Then input 380V/3phase to the spindle drive, and see if the alarm still there?

Please take photo of the connection and alarm for us, thanks.

   I connected only T and R with 380 V/3 phase to the spindle drive and it shows an Error in its display as error-3 and error-9. Please check the attachments along with this mail and reply me. Thanks

Alarm 9 is normal, because it is not connect to spindle encoder.

If the alarm 3 shows immediately after turn on the power. There must be two possibilities.

1-input power has problem, lacking phase, etc.

2-If you are sure the input power is fine. Then the spindle driver must be broken.
