Press the Key if the stroke is
set to a positive value, or press the
Key if the stroke is set to a
negative value.
Calculation of the moment of inertia
will start.
While the moment of inertia is being
calculated, the setting of Pn103 will
flash and 1:ADJ will flash instead of
1:RUN.
When calculating the moment of
inertia has been completed, the dis-
play will stop flashing and the
moment of inertia will be displayed.
The servo will remain ON, but auto-
matic operation will stop temporar-
ily.
Note: 1. Calculating the moment of iner-
tia will not start if the sign of the
stroke does not agree with the
key that is pressed ( Key
or Key).
2. If Jcalc is set to OFF, calculat-
ing the moment of inertia will
not start and the setting of
Pn103 will be displayed.
3. If NO-OP or ERROR is dis-
played during operation, press
the Key to cancel the
