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
are satisfied.
Check if the detection conditions
are satisfied.
Check the setting of Pn002.3.
Check the capacities to see if they
satisfy the following condition:

Replace the servomotor and see if
the alarm occurs again.

Check the product specifications,
and select the correct model.

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).
Make sure the setting of Pn002.3
agrees with the fully-closed mod-
ule.
