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 A3-F
3.
models.)
Ensure the correct time sequence of sending packets from the controller.
4.
A drift or delay in packet sending time causes synchronization failure.
When the servo drive is in the operation mode of PV (Profile velocity mode),
5.
PT (Profile torque mode), or HM (Homing mode), check if P3.017 is set too
low.
NMT: reset node or OD 6040h [Bit 7] (Fault reset).
Condition: the servo drive cannot send the command when in IP mode (except the
CANopen B mode).
Cause: the interpolation command fails.
The computing time takes too long. Disable the USB monitoring function.
NMT: reset node or OD 6040h [Bit 7] (Fault reset).
Condition: CANopen 301 OD 1006h data error.
Cause: SYNC period is in error.
Check the value of OD 1006h. If it is smaller than or equal to 0, this alarm occurs.
NMT: reset node or OD 6040h [Bit 7] (Fault reset).
The rising edge of DI: 0x47 is triggered, and then the motor decelerates to 0 and
triggers AL3CF.
Check if the DI is set to 0x47 with any of the parameters, P2.010 - P2.017 and
P2.036 - P2.040, and is triggered.
Cycle power on the servo drive.
