5.2 How to Calculate the Linear Displacement
The DRV series motors have 200 full steps per revolution and when driven by the BSC20x or MST602 drivers there are 2048
microsteps per full step, giving 409,600 microsteps per revolution of the motor lead screw. The lead screw pitch is 1.0 mm
The linear displacement of the lead screw per microstep:
1 / 409600 = 2.4 x 10

a.
The average of the repeatability when a set position is approached from both directions.
b.
When a stage is moved to a position and then returned to its original position, some motion is lost
due to the lead screw mechanism. This loss is known as backlash.
c.
The measured minimum incremental motion that the stage can achieve, also referred to as the
minimum step size.
d.
If Used with a BSC201, BSC202, or BSC203 Controller
e.
The minimum incremental motion that the stage can repeatedly achieve within its standard error.
f.
Under Continuous Use
g.
When DRV250 actuator is fully extended.
