APPENDIX
[Setting example]
Obtain the command pulse frequency required to run the HG-KR at 3000 r/min.
The following result will be found according to equation 5.6.

= 209715200 [pulses/s]
However, as the maximum input command pulse frequency in the differential line driver type is 4 Mpulses/s
for MR-J4 servo amplifier, 209715200 pulses/s cannot be entered.
To run the servo motor at the speed of 3000 r/min at not more than 4 Mpulses/s, the electronic gear setting
must be changed. This electronic gear is found by equation 5.5.

Therefore, the parameters are set to CMX = 32768 and CDV = 625.
