(Note)
When using an electronic gear, it is necessary to change the
setting value.
For simultaneous replacement, set a value by calculating as
follows:

When a geared servo motor is replaced, the actual reduction
ratio may differ before and after the replacement. If the ratio
differs after the replacement, set the values considering the
actual reduction ratio.
PA07
Electronic gear denominator
(Commanded pulse
multiplication denominator)
1 1
(Note)
PA13
Command pulse input form
0 1 0 0h _ x _ _h Command input pulse train filter selection
Selecting the proper filter enables noise immunity enhancement.
Make sure to select a filter so as not to cause a position
mismatch. For details, refer to "MR-J4-_A_ [Pr. PA13]" in
Section 3.6.3.
In addition, it is necessary to adjust the command pulse logic to
the positioning module. An incorrect logic setting causes the
servo motor to not rotate. Make sure to configure the settings.
Refer to "3.7 Important Points for Replacement (Command
Pulse Logic Settings)".
Note. The example value shown is for when the electronic gear ratio of an existing servo amplifier is set as "8/1".
