AL289 Feedback position counter overflows
Trigger condition
and causes
Feedback position counter overflows.
Checking methods
and corrective
actions
1.
Please set the gear ratio according to the total traveling distance of the
absolute motor and the actual application requirements to avoid the
feedback position counter overflow.
2.
If P2.069.Z is set to 1 (prevent index coordinate overflow function),
please set P2.070 bit 2 to 1.
How to clear the
alarm?
NMT: reset node or 0x6040 (fault reset).
AL380 Position offset alarm for DO.MC_OK
Trigger condition
and causes
DO.MC_OK is on and then goes off.
Checking methods
and corrective
actions
Please refer to the description of P1.048. After DO.MC_OK is on,
DO.MC_OK goes off because DO.TPOS turns off. There might be an
external force causing the position deviation of the motor after positioning is
completed. You can disable this alarm by setting P1.048.Y to 0.
How to clear the
alarm?
DI.ARST or set P0.001 to 0.
AL3F1 Absolute index coordinate undefined
Trigger condition
and causes
Condition: in communication mode (CANopen, DMCNET, and EtherCAT),
an absolute positioning command is issued before absolute coordinate
system is created.
Causes:
1. The absolute coordinate system has not been created.
2. Overflow occurs since the motor keeps rotating in the same direction.
Checking methods
and corrective
actions
1. Create an absolute coordinate system.
2. Set the coordinate system origin again.
How to clear the
alarm?
Set the origin again.
