Position Error
Overflow Alarm by
Speed Limit at Servo
ON
When the position errors remain
in the error counter, Pn529 limits
the speed if the servomotor power
is 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).
−
Set position error to be cleared
while the servomotor power is OFF.
Or, correct the excessive position
error alarm level (Pn520).
Or, adjust the speed limit level at
servo ON (Pn529).
CPF00:
Digital Operator
Transmission Error 1
The contact between the digital
operator and the SERVOPACK is
faulty.
Check the connector contact.
Insert securely the connector or
replace the cable.
Malfunction caused by noise
interference.
−
Keep the digital operator or the
cable away from noise sources.
CPF01:
Digital Operator
Transmission Error 2
A digital operator fault occurred.
−
Disconnect the digital operator and
then re-connect it. If the alarm still
occurs, the digital operator may be
faulty. Replace the digital operator.
A SERVOPACK fault occurred.
−
Restart the SERVOPACK. If the
alarm still occurs, the SERVO-
PACK may be faulty. Replace the
SERVOPACK.
∗4.
