A.040:
Parameter Setting
Error 1
(The parameter setting
was out of the setting
range.)
The SERVOPACK capacity, con-
verter capacity, and the servomo-
tor capacity do not match each
other.
Check the combination of SERVO-
PACK, converter, and servomotor
capacities.
Select the proper combination of
capacities.
A fault occurred in the multi-
winding drive unit.
−
The multi-winding drive unit may
be faulty. Replace the multi-wind-
ing drive unit.
The parameter setting is out of
the setting range.
Check the setting ranges of the
parameters that have been changed.
Set the parameter to a value within
the setting range.
The electronic gear ratio is out of
the setting range.
Check the electronic gear ratio. The
ratio must satisfy:
0.001< (Pn20E/Pn210) < 4000.
Set the electronic gear ratio in the
range: 0.001< (Pn20E/Pn210)
< 4000.
A.041:
Encoder Output Pulse
Setting Error
The encoder output pulse (Pn212)
is out of the setting range and
does not satisfy the setting condi-
tions.
Check the parameter Pn212.
Set Pn212 to a correct value.
A.042:
Parameter
Combination Error
The speed of program JOG oper-
ation (Fn004) is lower than the
setting range after having
changed the electronic gear ratio
(Pn20E/Pn210) or the servomo-
tor.
Check if the detection conditions
*
are 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 range after having
changed the setting of the pro-
gram JOG movement speed
(Pn533).
Check if the detection conditions
*
are satisfied.
Increase the setting of the program
JOG movement speed (Pn533).
The moving speed of advanced
autotuning is lower than the set-
ting range after having changed
the electronic gear ratio (Pn20E/
Pn210) or the servomotor.
Check if the detection conditions
*
are satisfied.
Decrease the setting of the elec-
tronic gear ratio (Pn20E/Pn210).
A.045:
Multi-winding Drive
Unit Parameter Set-
ting Error
The parameter setting does not
match the number of SERVO-
PACK axes that are connected.
Check the setting of Pn002.3.
Make sure the setting of Pn002.3
agrees with the fully-closed mod-
ule.
A.050:
Combination Error
(The SERVOPACK and
servomotor 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
SERVOPACK and servomotor
capacities.
An encoder fault occurred.
Replace the servomotor and see if
the alarm occurs again.
Replace the servomotor (encoder).
A fault occurred in the SERVO-
PACK or converter.
−
The SERVOPACK or converter
may be faulty. Replace the SERVO-
PACK or converter.
A.051:
Unsupported Device
Alarm
An unsupported serial converter
unit, encoder, or external encoder
is connected to the multi-winding
drive unit.
Check the product specifications,
and select the correct model.
Select the correct combination of
units.
