How to clear the
alarm?
Condition: the target position specified by the command exceeds the software
negative limit.
Cause: the software negative limit is triggered.
The software negative limit is determined by the Position command instead of the
actual feedback position because the command is sent before the feedback is
received. That is, the actual position may not have exceeded the limit when this limit
protection is enabled. Set the appropriate deceleration time to achieve the desired
effect. For more information, refer to the descriptions of P5.003.
The alarm is automatically cleared after moving away from the limit.
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 (prevent index coordinate overflow function), set P2.070
2.
bit 2 to 1.
DI.ARST
Condition: the servo drive fails to synchronize with the controller in CANopen IP
mode.
Cause: CANopen synchronization failure.
Make sure the communication quality is good.
1.
After eliminating any problems that you find, allow the controller to re-send the
2.
SYNC signal and ensure that it is sent successfully.
Modify the setting for P3.009 (setting the default value is suggested).
3.
NMT: reset node or 0x6040 fault reset.
Condition: command cannot be sent when in CANopen IP mode.
Cause: invalid CANopen IP command.
The computing time in IP mode takes too long. Disable the USB monitoring function.
NMT: reset node or 0x6040 fault reset.
