STROKE (Travel Distance) Setting
The travel distance setting range is from -99,990,000 to +99,990,000 [reference units].
Specify the STROKE (travel distance) in increments of 1,000 reference units.
The negative (-) direction is for reverse rotation, and the positive (+) direction is for forward rotation.
Initial value: About 3 rotations
Note 1. Set the number of motor rotations to at least 0.5.
If you do not, “Error” will be displayed and the travel distance cannot be set.
2. To calculate the moment of inertia accurately, it is recommended to set the number of motor rotations
to around 3.
4
Press the
Key. The moment of inertia ratio
calculation execution screen will be displayed.
5
Press the
Key. The servomotor power will be
turned ON and the display will change from “BB” to
“RUN.”

Display example:
After the moment of inertia is
calculated.
The moment of inertia is calculated.
Press the
Key if a positive (+) value is set in
STROKE (travel distance), or press the
Key if a
negative (-) value is set. Calculation of the moment of
inertia will start.
While the moment of inertia is being calculated, the
set value for Pn103 will flash and “ADJ” will flash
instead of “RUN.”
When calculating the moment of inertia is completed,
the display will stop flashing and the moment of iner-
tia will be displayed. The servomotor will remain
ON, but the auto run operation will be stopped tem-
porarily.
Note:
• If the wrong key (i.e.,
or
Key) is pressed
for the set STROKE (travel direction), the calcula-
tion will not start.
• If “NO-OP” or “Error” is displayed during opera-
tion, press the
Key to cancel the function.
Refer to
(2)Failure in Operation
and take a correc-
tive action to enable operation.
7
After the servomotor is temporarily stopped, press the
Key to save the calculated moment of inertia
ratio in the multi-winding drive unit.
“DONE” will flash for one second, and “ADJ” will
be displayed again.
Press the
Key to end the operation.
8
Turn the control power supply OFF and ON again.
