Cause Investigative Actions
Check the combination of SERVO-
PACK and servomotor capacities.
−
Check the setting ranges of the
parameters that have been changed.
Check the electronic gear ratio. The
ratio must satisfy:
0.001< (Pn20E/Pn210) <4000.
Check the parameter Pn281.
Check that the detection conditions
is satisfied.
Check that the detection conditions
is satisfied.
Check that the detection conditions
is satisfied.
Check the settings of the option
module, Pn00B.3, and Pn002.3.
Check the capacities to see if they
satisfy the following condition:
(Servomotor capacity)/(SERVO-
PACK capacity) ≤ 1/4, or (Servo-
motor capacity)/(SERVOPACK
capacity) ≤ 4.
Replace the servomotor and see if
the alarm occurs again.
−
Check the product specifications,
and select the correct model.

The SERVOPACK may be faulty.
Repair or replace the SERVO-
PACK.
Set the parameter to a value within
the specified range.
Set the electronic gear ratio in the
range: 0.001< (Pn20E/Pn210)
<4000.
Set Pn281 to a correct value.

(Pn20E/Pn210).
The setting of option module must
be compatible with the settings of
Pn00B.3 and Pn002.3.
Mount an option module or replace
the mounted option module with an
appropriate model. Or change the
parameter setting.
Select the proper combination of
SERVOPACK and servomotor
capacities.
Replace the servomotor (encoder).
The SERVOPACK may be faulty.
Repair or replace the SERVO-
PACK.
Select the correct combination of
