A.041:
Encoder Output Pulse
Setting Error
The encoder output resolution
(Pn281) is out of the setting range
and does not satisfy the setting
conditions.
Check the parameter Pn281. Set Pn281 to a correct value.
A.042:

Parameter Combina-
tion Error
The speed of program JOG oper-
ation (Fn004) is lower than the
setting rang
e after having
changed the electronic gear ratio
(Pn20E/Pn210) or the servomo-
tor.
Check if the detection conditions
a
re satisfied.
Decrease the setting of the elec-
tronic gear ratio (Pn20E/Pn210).
The speed of program JOG oper-
ation (Fn004) is lower than the
setting rang
e after having
changed the setting of the pro-
gram JOG movement speed
(Pn585)
.
Check if the detection conditions
are satisfied.
Increase the setting of the program
JOG movement speed (Pn585).
The moving speed of advanced
aut
otuning is lower than the set-
ting range after having changed
the electr
onic gear ratio (Pn20E/
Pn210) or the servomotor.
Check if the detection conditions
a
re satisfied.
Decrease the setting of the elec-
tronic gear ratio (Pn20E/Pn210).
A.050:
Combination Error
(The SERVOPACK and
serv
omotor capacities do
not correspond.)
The SERVOPACK and servomo-
tor capacities do not match each
other
.
Check the capacities to see if they
satisfy the following condition:
Select the proper combination of
SER
VOPACK and servomotor
capacities.
A linear scale fault occurred.
Replace the linear scale and see if
t
he alarm occurs again.
Replace the linear scale.
A SERVOPACK fault occurred.
The SERVOPACK may be faulty.
Replace the SERVOPACK.
A.051:
Unsupported Device
Alarm
The parameters of the motor
para
meter file are not written in
the linear scale. (Only when not
using serial converter units)
Check if the parameters of the
m
otor parameter file are written in
the linear scale.
Write the parameters of the motor
par
ameter file in the linear scale.
An unsupported serial converter
unit
or linear scale is connected to
the SERVOPACK.
Check the product specifications,
and s
elect the correct model.
Select the correct combination of
units.
A.080:
Linear Scale
Pitch Setting
Error
The setting of the linear scale
pitch (Pn282) has not been
changed from the default setting.
Check the value of Pn282. Correct the value of Pn282.
A.0b0:
Cancelled Servo ON
Command Alarm
After executing the utility func-
tion to turn ON the power to the
motor
, the servo ON signal (/S-
ON) was sent from the host con-
troller.
Turn the SERVOPACK power sup-
ply OFF and then ON again or exe-
cute a software reset.
