Simplified Positioning System Design
The figure below shows the positioning which uses a stepping motor.
Stepping motor Reduction gear ratio Moving object
The formula below describes the travel distance per pulse relative to the motor driver which is
called pulse rate.
Pulse rate =
You can calculate the number of pulses required to move the load by L (mm) as follows from
the pulse rate:
Number of pulses =
The pulse speed required to move the load at the feed speed of V mm/second is as follows:
Pulse speed =
The PCU gives the above number of pulses and pulse speed as a position command and a
speed command, respectively, to perform positioning control.
