PA05 Number of command input pulses per revolution
Turn off the power and then on again after setting
the parameter to validate the parameter value.
When "0" (initial value) is set in [Pr. PA05], the
electronic gear ([Pr. PA06, PA07]) is made valid.
When the setting is other than "0", that value is
used as the command input pulses necessary to
rotate the servo motor one turn. At this time, the
electronic gear is made invalid.

1000 to 50000
Number of command input
pulses necessary to rotate the
servo motor one turn [pulse]
0 PA05 Number of command input pulses per revolution
The servo motor rotates based on set command
input pulses.
To enable the parameter value, set "Electronic gear
selection" to "Number of command input pulses per
revolution (1 _ _ _)" of in [Pr. PA21].
Setting range: 1000 to 1000000

Incorrect setting can lead to unexpected fast
rotation, causing injury.

<
CDV

< 2000
If the set value is outside this range, noise may be
generated during acceleration/ deceleration or
operation may not be performed at the preset speed
and/or acceleration/deceleration time constants.
Always set the electronic gear with servo off state to
prevent unexpected operation due to improper
setting.
Concept of electronic gear
The machine can be moved at any multiplication
factor to input pulses.
