AL303 CANopen synchronization signal timeout
Trigger condition
and cause
Condition: the synchronization with the controller fails when you use the CANopen
IP mode (in B mode).
Cause: timeout of CANopen synchronization signal.
Checking method
and corrective action
1.
Make sure the communication between the servo drive and controller is good.
2.
Make sure the setting of synchronization cycle (0x1006) is identical to that of
the controller.
3.
Modify the synchronization error range setting (P3.009.U).
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) or
HM (Homing mode), check if P3.017 is set too low.
How to clear the
alarm?
NMT: reset node or 0x6040 fault reset.
AL305 SYNC period error
Trigger condition
and cause
Condition: CANopen 301 Obj 0x1006 Data Error.
Cause: SYNC period is in error.
Checking method
and corrective action
Check the value of 0x1006. If it is smaller than or equal to 0, this alarm occurs.
How to clear the
alarm?
NMT: reset node or 0x6040 fault reset.
AL304 Invalid interpolation mode command
Trigger condition
and cause
Condition: the servo drive cannot send the command when in CANopen IP mode
(except in 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 0x6040 fault reset.
AL35F Emergency stop during deceleration
Trigger condition
and cause
The rising edge of DI(0x47) is triggered, and then the motor decelerates to 0 and
triggers AL3CF.
Checking method
and corrective action
Check if any of the parameters, P2.010 - P2.017 and P2.036 - P2.040, is set to
DI(0x47) and is triggered.
How to clear the
alarm?
Cycle power on the servo drive.
