DO.MC_OK is on and then goes off.
Refer to the description of P1.048. DO.MC_OK is on, but then it 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 any of the parameters, P2.010 - P2.017 and P2.036 - P2.040, is set to
DI(0x47) and is triggered.
Cycle power on the servo drive.
Condition: the communication synchronization with the controller fails in CANopen
IP mode (except in 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 0x6040 fault reset.
Condition: the synchronization signal is received too early.
Cause: the communication synchronization signal is sent too soon.
Make sure the setting of synchronization cycle (0x1006) is identical to that of
1.
the controller.
Modify the synchronization error range setting (P3.009.U).
2.
Ensure the correct time sequence of sending packets from the controller.
3.
A drift or delay in packet sending time causes synchronization failure.
NMT: reset node or 0x6040 fault reset.
