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.
Check if the detection conditions
*
are satisfied.
Reduce the electronic gear ratio
(Pn20E/Pn210).
The speed of program JOG oper-
ation (Fn004) is lower than the
setting range after having
changed the setting of Pn585
“Program JOG Movement
Speed.”
Check if the detection conditions *
are satisfied.
Increase the setting for Pn585 “Pro-
gram 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.
Check if the detection conditions *
are satisfied.
Reduce the electronic gear ratio
(Pn20E/Pn210).

Error
The setting of the option module
does not match with that of
Pn002.3.
Check the settings of Pn002.3.
The setting of option module must
be compatible with the settings of
Pn002.3.

Combination Error
(The SERVOPACK and
servomotor capacities do
not correspond.)
The SERVOPACK and linear ser-
vomotor capacities do not match
each other.
Check the capacities if they satisfy
the following equation:
1/4
≤ (Linear servomotor capacity)/
(SERVOPACK capacity) ≤ 4.
Select the proper combination of
SERVOPACK and linear servomo-
tor capacities.
A linear scale fault occurred.
Replace the linear servomotor and
see if the alarm occurs again. Replace the linear servomotor (lin-
ear scale).
A SERVOPACK fault occurred. −
The SERVOPACK may be faulty.
Replace the SERVOPACK.
