Defaul Setup
* Our default setup is “the motor shaft rotates once at
10000 pulse input”. Note that the maximum input pulse
frequency is 500 kpps for a line driver and 200 kpps for
an open collector.
(Example 1) Rotate the motor at 60 degrees with overall deceleration ratio of 18/365.
* Also refer to “Description on Dividing/Multiplier
Ratio” on Page 178 of Reference edition.
* You can set any value depending on a numerator and denominator setting. However, if you specify
an extreme dividing/multiplier ratio, we cannot guarantee proper operation of the motor. We
recommend that you set the dividing/multiplier ratio in the range of to 20 times.
