∗1. Detection conditions
If one of the following conditions detected, an alarm occurs.
Pn533 [min
•
Max Motor Speed [min
•
Cause
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 settings of Pn002.3.
–
Check the capacities to see if they
satisfy the following condition:

Investigative Actions
Set Pn212 to a correct value.
*1
Decrease the setting of the elec-
tronic gear ratio (Pn20E/Pn210).
*1
Increase the setting of the program
JOG movement speed (Pn533).
*1
Decrease the setting of the elec-
tronic gear ratio (Pn20E/Pn210).
The setting of fully-closed module
must be compatible with the setting
of Pn002.3.
Set the following reserved parame-
ters to the factory settings.

capacities.
SERVOPACK capacity
Replace the servomotor (encoder).
The SERVOPACK or converter
may be faulty. Replace the SERVO-
PACK or converter.
Select the correct combination of
units.
Turn the SERVOPACK power sup-
ply OFF and then ON again or exe-
cute a software reset.
