Trigger condition
and cause
Position counter overflows.
Set the gear ratio according to the actual application requirements and the
1.
total traveling distance of the absolute motor to avoid overflow of the feedback
counter.
If P2.069.Z is set to 1 (enabling the function of preventing the rotary axis
2.
position from being lost when overflow occurs), set P2.070 [Bit 2] to 1 (no
overflow warning).
DI.ARST
Condition: the synchronization with the controller fails when you use the CANopen
IP mode (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 when you use the
CANopen IP mode (B mode).
Cause: the synchronization signal of CANopen 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.
NMT: reset node or OD 6040h [Bit 7] (Fault reset).
Condition: the synchronization with the controller fails when you use the CANopen
IP mode (B mode).
Cause: timeout of CANopen synchronization signal.
