A.041
Dividing Pulse
Output Setting
Error
Occurred when the
control power
supply was turned
ON.
The PC dividing pulse set for Pn212 is out of the
setting range and does not satisfy the setting
conditions.
Set Pn212 to the correct value.
A.042
Multiple
Parameter
Combinations
Exceeding Set
Range
Occurred when the
power was turned
ON again after
changing electronic
gear ratio (Pn20E/
Pn210) or changing
the motor to the one
with different
number of encoder
pulses.
Speed of program JOB operation (Fn004) is out of
range by changing electronic gear ratio (Pn20E/
Pn210) or motor.
Reduce electronic gear ratio (Pn20E/Pn210).
Occurred when
program JOG
movement speed
(Pn533) is changed.
Speed of program JOB operation (Fn004) is out of
range by changing program JOG movement speed
(Pn533).
Increase program JOG movement speed (Pn533).
Occurred when
attempting to
execute advanced
autotuning (F017)
after changing
electronic gear ratio
(Pn20E/Pn210) or
changing the motor
to the one with
different number of
encoder pulses.
Movement speed of advanced autotuning is out of
range by changing electronic gear ratio (Pn20E/
Pn210) or motor.
Reduce electronic gear ratio (Pn20E/Pn210).
A.050
Combination
Error
Occurred when the
control power
supply was turned
ON.
The SERVOPACK and servomotor capacities do not
correspond to each other.
Servomotor capacity / SERVOPACK capacity ≤ 1/4
or servomotor capacity / SERVOPACK capacity ≥ 4
Select the proper combination of SERVOPACK
and servomotor capacities.
The parameter that is written in the encoder is
incorrect.
Replace the servomotor (encoder).
A SERVOPACK board fault occurred. Replace the SERVOPACK.
