Condition: in CANopen IP mode, the synchronization with the controller
failed.
Cause: timeout of CANopen synchronization signal.
1. Make sure the communication quality is good.
2. Make sure the setting of synchronization cycle (0x1006) is identical to
that of the controller.
3. Modify the setting of P3.009 (using default value is suggested).
4. Ensure the correct time sequence for sending packets from the
controller. A drift or delay in packet sending time causes synchronization
failure.
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. Please disable the USB
monitoring function.
NMT: reset node or 0x6040 (fault reset).
Condition: CANopen 301 Obj 0x1006 Data Error
Cause: SYNC period error.
Check the value of 0x1006. If it is smaller than or equal to 0, the alarm
occurs.
NMT: reset node or 0x6040 (fault reset).
NMT reset command is received while servo drive is on.
Check if the NMT reset command is received while the servo drive is on.
Use NMT.reset or 0x6040 (fault reset).
