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
card, 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.

Select the proper combination of
SERVOPACK and servomotor
capacities.
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.
Reduce the electronic gear ratio

gram JOG Movement Speed."
Reduce the electronic gear ratio
*1
(Pn20E/Pn210).
The setting of option card must be
compatible with the settings of
Pn00B.3 and Pn002.3.
Mount an option card or replace the
mounted option card with an appro-
priate model. Or change the param-
eter setting.
Change the settings for bank mem-
bers to an appropriate value.
Reduce the total amount of bank
data to 64 or less.
Select the proper combination of
SERVOPACK and servomotor
capacities.
Replace the servomotor (encoder).
The SERVOPACK may be faulty.
Repair or replace the SERVO-
PACK.
