Meaning
Different multiturn limits have been set in
the encoder and the SERVOPACK.
Reception from the Feedback Option
Module is faulty.
Timer for communications with the Feed-
back Option Module is faulty.
Position error exceeded the value of exces-
sive position error alarm level (Pn520)
when the servomotor power is ON.
This alarm occurs if the servomotor power
is turned ON when the position error is
greater than the set value of Pn526 while
the servomotor power is OFF.
When the position errors remain in the
error counter, Pn529 limits the speed if the
servomotor power is turned ON. If Pn529
limits the speed in such a state, this alarm
occurs when reference pulses are input and
the number of position errors exceeds the
value set for the excessive position error
alarm level (Pn520).
During fully-closed loop control, the posi-
tion error between motor and load is
excessive.
Detection of the safety option module
failed.
Detection of the Feedback Option Module
failed.
An unsupported safety option module was
connected.
An unsupported feedback option module
was connected.
–
The safety function signal input timing is
faulty.
–
–
With the main circuit power supply ON,
voltage was low for more than 1 second in
phase R, S, or T.
An error occurred in the operation of the
dynamic brake contactor.
Internal program error occurred in the
SERVOPACK
