Alarm Meaning
If position deviation remains in the deviation
counter, the setting of Pn529 or Pn584 (Speed
Limit Level at Servo ON) limits the speed when
the servo is turned ON. This alarm occurs if a
position reference is input and the setting of
Pn520 (Position Deviation Overflow Alarm Level)
is exceeded before the limit is cleared.
There was too much position deviation between
the motor and load during fully-closed loop con-
trol.
The position feedback data exceeded
±1,879,048,192.
The difference between the clearance offset ref-
erence and gap exceeded Pn6FC (Clearance
Position Deviation Error Level).
A synchronization error occurred during
MECHATROLINK communications with the SER-
VOPACK.
The setting of the MECHATROLINK communica-
tions transmission cycle is not correct.
The setting of the MECHATROLINK communica-
tions data size is not correct.
The setting of the MECHATROLINK station
address is not correct.
A synchronization error occurred during
MECHATROLINK communications.
Synchronization failed during MECHATROLINK
communications.
Communications errors occurred continuously
during MECHATROLINK communications.
An error occurred in the transmission cycle
during MECHATROLINK communications.
Synchronization frames were continuously not
received during MECHATROLINK communica-
tions.
Detection of the Safety Option Module failed.
Detection of the Feedback Option Module failed.
An unsupported Safety Option Module was con-
nected.
An error occurred in the input timing of the safety
function signal.
An error occurred in the gate drive circuit.
An error occurred in the gate drive circuit.
A timeout error occurred for a MECHATROLINK
command.
The voltage was low for more than one second
for phase R, S, or T when the main power supply
was ON.
