Only when safety function is used.
Meaning
Position error pulses exceeded parameter
(Pn520).
Position error pulses accumulated too
much.
If the servo turns ON with position error
pulses accumulated, the speed is limited by
Pn529. In this state, the reference pulse was
input without resetting the speed limit, and
the position error pulses exceeds the value
set for the parameter Pn520.
The position data exceeded ±1879048192.
The safety function signal input timing is
faulty.
With the main power supply ON, voltage
was low for more than 1 second in phase-R,
-S or -T.
Digital operator (JUSP-OP05A) fails to
communicate with the SERVOPACK (e.g.,
CPU error).
