Meaning
"Internal program error 3" of the SERVO-
PACK occurred.
"Internal program error 4" of the SERVO-
PACK occurred.
The servomotor ran out of control.
The detection of the phase is incorrect.
The hall sensor is faulty.
The phase information does not match.
The polarity detection failed.
The overtravel signal was detected at polarity
detection.
The servo was turned ON under the condition
of polarity detection uncompleted.
The moving distance exceeded the set value of
Pn48E during polarity detection.
The polarity detection failed.
The multi-turn for the absolute encoder was
not properly cleared or set.
Communications between the SERVOPACK
and the encoder is not possible.
An encoder position data calculation error
occurred.
An error occurs in the communications timer
between the encoder and the SERVOPACK.
Encoder parameters are faulty.
Contents of communications with encoder is
incorrect.
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 was input
without resetting the speed limit, and the posi-
tion error pulses exceeds the value set for the
parameter Pn520.
The position data exceeded ±1879048192.
Synchronization error during MECHA-
TROLINK-II communications with the SER-
VOPACK.
The setting of the MECHATROLINK-II
transmission cycle is out of the allowable
range.
A synchronization error occurs during
MECHATROLINK-II communications.
A synchronization failure occurs in MECHA-
TROLINK-II communications.
A communications error occurs continuously
during MECHATROLINK-II communica-
tions.
