Note
The setting value must be changed based on machine
resonance frequency.
The setting value needs to be changed according to the
auto tuning mode. Some of the settings cannot be set.

The setting value must be changed according to resolution
and detection capability.
Set it per command input pulse before electronic gear
conversion for both MR-J2M-A and MR-J4-_A_.
The unit system is different. (rad/s→0.1 rad/s)
Change the setting value as necessary.
Max. output frequency is different.
The unit system is different.
(0.1-fold→0.01-fold)
Pay attention to the setting value.
No corresponding parameter (Setting not required)
The unit system is different. (ms → 0.1 ms)
