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:
*1
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
(Pn585).
Check if the detection conditions
*
are satisfied.
Increase the setting of the program
JOG movement speed (Pn585).
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.04A:
Parameter Setting
Error 2
For a 4-byte parameter bank, no
registration in two consecutive
bytes for two bank members.
–
Change the number of bytes for
bank members to an appropriate
value.
The total amount of bank data
exceeds 64. (Pn900
×
Pn901 >
64)
–
Reduce the total amount of bank
data to 64 or less.
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.
A linear scale fault occurred.
Replace the linear scale and see if
the 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
parameter file are not written in
the linear scale. (Only when not
using serial converter units)
Check if the parameters of the
motor parameter file are written in
the linear scale.
Write the parameters of the motor
parameter file in the linear scale.
An unsupported serial converter
unit or linear scale is connected to
the SERVOPACK.
Check the product specifications,
and select 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 command
(SV_ON) was sent from the host
controller.
−
Turn the SERVOPACK power sup-
ply OFF and then ON again or exe-
cute a software reset.
