The target command is not received within a continuous communication cycle in IP
mode (except the CANopen B mode).
Make sure the communication between the servo drive and controller is good.
1.
Make sure the setting of communication cycle period (OD 1006h) is identical
2.
to that of the controller.
Modify the synchronization error range setting (P3.009.U). (For A3-M and
3.
A3-F models.)
Modify the setting of IP command timeout (P3.022.YX). (For A3-E models.)
4.
Ensure the correct time sequence of sending packets from the controller.
5.
A drift or delay in packet sending time causes synchronization failure.
NMT: reset node or OD 6040h [Bit 7] (fault reset).
Condition: when the bus communication type (CANopen, DMCNET, and
EtherCAT) servo drive is in combination with an incremental motor and the position
overflow occurs with the absolute origin position not established, the absolute
positioning command is issued.
Cause:
The absolute origin position is not established.
1.
Overflow occurs since the motor keeps rotating in the same direction.
2.
Establish the absolute origin position.
Establish the absolute origin position.
Condition: the position offset of the motor in 1 ms exceeds the setting of P2.052
(Rotary axis position scale).
Cause: the value of P2.052 is set too small.
Check if P2.052 is set according to the specifications in the manual.
