b) Determine the position controller to be used in accordance with the output pulse
frequency.
However, the pulse frequency actually used inside the servo amplifier can be increased
by electronic gearing.
c) Determine the position controller to be used in accordance with handling of the feedback
pulse.

To servo amplifier
The position controller only outputs pulses,
and does not check feedback pulses.
Accordingly, it is not confirmed whether or
not rotation in accordance with command
pulses is actually performed.
