Alarm Meaning
There is an internal data error
in the encoder.
The encoder was operating
at high speed when the
power was turned ON.
The internal temperature of
the rotary encoder or linear
encoder is too high.
The internal temperature of
motor is too high.
A failure occurred in the lin-
ear encoder.
An error occurred in the lin-
ear encoder.
An error occurred in the
external encoder.
An error occurred in the
Serial Converter Unit.
An error occurred in the
external encoder.
An error occurred in the posi-
tion data of the external
encoder.
An overspeed error occurred
in the external encoder.
An overheating error
occurred in the external
encoder.
An error occurred in the A/D
converter for the speed refer-
ence input.
An error occurred in the A/D
conversion data for the
speed reference.
An error occurred in the A/D
converter for the torque ref-
erence input.
An error occurred in the cur-
rent detection circuit.
Internal program error 0
occurred in the SERVO-
PACK.
Internal program error 1
occurred in the SERVO-
PACK.
Internal program error 2
occurred in the SERVO-
PACK.
Internal program error 3
