The first step in determining the stepper motor step angle, this motor will be indicated. For example, 1.8 degrees, a peripheral 360 / 1.8 = 200, i.e. revolution of the motor requires 200 pulses.
The second step determines the motor drive is provided without subdivision segments, identify the number of segments, DIP can be seen on the drive. 4 segments For example, if the upper bearing, 200 * 4 = 800, mean that only the pulse motor 800 rotation.
The third step is to determine the length of the motor shaft or lead week: If a screw pitch of the thread lead = number of heads, if a rack and pinion drive, the pitch circle diameter (m Z) is the lead, lead / = number of pulses of a line shift pulse.
