Alarm Name
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 linear ser-
vomotor.
The speed of program JOG oper-
ation (Fn004) is lower than the
A.042:
setting range after having
Parameter
changed the setting of Pn585
Combination Error
"Program JOG Movement
Speed."
The movement speed during
advanced autotuning is lower
than the setting range after having
changed the electronic gear ratio
(Pn20E/Pn210) or the linear ser-
vomotor.
A.044:
The setting of the option module
Semi-closed/Fully-
does not match with that of
closed Loop Control
Pn002.3.
Parameter Setting
Error
A.04A:
A parameter reserved by the sys-
Parameter Setting
tem was changed.
Error 2
The SERVOPACK and linear ser-
vomotor capacities do not match
A.050:
each other.
Combination Error
(The SERVOPACK and
A linear scale fault occurred.
servomotor capacities do
not correspond.)
A SERVOPACK fault occurred.

Detection conditions
If one of the following conditions is detected, an alarm occurs.
•
Linear scale pitch [μm]
Pn385 [100 mm/s]
•
Linear scale pitch [μm]
Cause
Check if the detection conditions
are satisfied.
Check if the detection conditions
are satisfied.
Check if the detection conditions
are satisfied.
Check the settings of Pn002.3.
–
Check the capacities if they satisfy
the following equation:
1/4 ≤ (Linear servomotor capacity)/
(SERVOPACK capacity) ≤ 4.
Replace the linear servomotor and
see if the alarm occurs again.

Investigative Actions
*
Reduce the electronic gear ratio
(Pn20E/Pn210).
*
Increase the setting for Pn585 "Pro-
gram JOG Movement Speed."
*
Reduce the electronic gear ratio
(Pn20E/Pn210).
The setting of option module must
be compatible with the settings of
Pn002.3.
Set the following reserved parame-
ters to the factory settings.
Select the proper combination of
SERVOPACK and linear servomo-
tor capacities.
Replace the linear servomotor (lin-
ear scale).
The SERVOPACK may be faulty.
Replace the SERVOPACK.
