DO.MC_OK is on and then goes off.
Refer to the description of P1.048. After DO.MC_OK is on, DO.MC_OK then goes
off because DO.TPOS turns off. There might be an external force causing the
position offset of the motor after positioning is complete. Disable this alarm by
setting P1.048.Y to 0.
DI.ARST
After AL35F is triggered and the motor has decelerated to 0, this alarm occurs.
Check if the DI is set to 0x47 with any of the parameters, P2.010 - P2.017 and
P2.036 - P2.040, and is triggered.
Cycle power on the servo drive.
Condition: the communication synchronization with the controller fails in IP mode
(except the CANopen B mode).
Cause: communication fails to synchronize.
Make sure the communication between the servo drive and controller is good.
1.
After eliminating any problems that you find, allow the controller to re-send the
2.
synchronization signal and ensure that it is sent successfully.
Modify the setting for P3.009 (the default value is suggested).
3.
NMT: reset node or OD 6040h [Bit 7] (Fault reset).
Condition: the synchronization signal is received too early.
Cause: the communication synchronization signal is sent too soon.
Make sure the setting of communication cycle period (OD 1006h) is identical
1.
to that of the controller.
Modify the synchronization error range setting (P3.009.U). (For A3-M and
2.
A3-F models.)
Ensure the correct time sequence of sending packets from the controller.
3.
A drift or delay in packet sending time causes synchronization failure.
