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 that the detection conditions
*1
is 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 Pn533
“Program JOG Movement
Speed.” Check that the detection conditions *1
is satisfied.
Increase the setting for Pn533 “Pro-
gram JOG Movement Speed.”
The moving speed during
advanced autotuning is lower
than the setting range after having
changed the electronic gear ratio
(Pn20E/Pn210) or the servomo-
tor.
Check that the detection conditions *1
is satisfied.
Reduce the electronic gear ratio
(Pn20E/Pn210).

Setting 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 servomo-
tor capacities do not match each
other.
Check the capacities if they satisfy
the following equation:
1/4
≤ (Servomotor capacity)/(SER-
VOPACK capacity) ≤ 4.
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 SERVOPACK fault occurred. −
The SERVOPACK may be faulty.
Replace the SERVOPACK.
