Troubleshooting

AL302 Synchronization signal of CANopen is sent too soon

3. Ensure the correct time sequence of sending packets from the controller.

A drift or delay in packet sending time causes synchronization failure.

How to clear the

alarm?

NMT: reset node or OD 6040h [Bit 7] (Fault reset).

AL303 CANopen synchronization signal timeout

Trigger condition

and cause

Condition: the synchronization with the controller fails when you use the CANopen

IP mode (B mode).

Cause: timeout of CANopen synchronization signal.

1. Make sure the communication between the servo drive and controller is good.

2. Make sure the setting of communication cycle period (OD 1006h) is identical

to that of the controller.

3. Modify the synchronization error range setting (P3.009.U). (For A3-M and A3-F

Checking method

models.)

and corrective action 4. Ensure the correct time sequence of sending packets from the controller.

A drift or delay in packet sending time causes synchronization failure.

5. When the servo drive is in the operation mode of PV (Profile velocity mode),

PT (Profile torque mode), or HM (Homing mode), check if P3.017 is set too

low.

AL304 Invalid interpolation mode command

Trigger condition

and cause

Condition: the servo drive cannot send the command when in IP mode (except the

CANopen B mode).

Cause: the interpolation command fails.

Checking method

and corrective action

The computing time takes too long. Disable the USB monitoring function.

How to clear the

alarm?

NMT: reset node or OD 6040h [Bit 7] (Fault reset).

AL305 SYNC period error

Trigger condition

and cause

Condition: CANopen 301 OD 1006h data error.

Cause: SYNC period is in error.

Checking method

and corrective action

Check the value of OD 1006h. If it is smaller than or equal to 0, this alarm occurs.

How to clear the

alarm?

NMT: reset node or OD 6040h [Bit 7] (Fault reset).
