Detection conditions
If one of the following conditions detected, an alarm occurs.
Pn533 [min
•
Max Motor Speed [min
•
Cause
Check the combination of SERVO-
PACK, converter, 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 Pn212.
Check if the detection conditions
are satisfied.
Check if the detection conditions

Check if the detection conditions
are satisfied.
• Check if the power is supplied to
the SERVOPACK.
• Check the connection of the local
communications cable.

Investigative Actions
Select the proper combination of
capacities.
The multi-winding drive unit may
be faulty. Replace the multi-wind-
ing drive unit.
Set the parameter to a value within
the setting range.
Set the electronic gear ratio in the
range: 0.001< (Pn20E/Pn210)
< 4000.
Set Pn212 to a correct value.
*
Decrease the setting of the elec-
tronic gear ratio (Pn20E/Pn210).
*
Increase the setting of the program
JOG movement speed (Pn533).
*
Decrease the setting of the elec-
tronic gear ratio (Pn20E/Pn210).
Change the number of bytes for
bank members to an appropriate
value.
Reduce the total amount of bank
data to 64 or less.

Corrective Actions
• Perform the wiring so that the
control power supply to the
multi-winding drive unit and
SERVOPACK is turned ON at the
same time.
• Connect the local communica-
tions cable correctly.
