Defining the reference system

Unit
Travel distance per
motor revolution /
pitch
Input as numerator
and denominator
Example 1:
104
The reference system for positioning is defined by:
a unit,

the travel distance per motor revolution,

a machine zero point with true zero,

positive and negative end limits.

Measure reference

In this chapter you can read about:
You can select from among the following for the unit:
mm,

increments *

angle degrees or

Inch.

The unit of measure is always [mm] for linear motors.
*
The unit "increments" is valid only for position values!
Speed, acceleration and jerk are specified in this case in revolutions/s,
2
revolutions/s and revolutions/s
The measure reference to the motor is created with the value:
"travel distance per motor revolution / pitch" in the selected unit.
You can enter the "travel distance per motor revolution" as a fraction (numerator
divided by denominator). This is useful in the case of continuous operation mode or
in reset mode if the value cannot be specified as a rational number. This makes it
possible to avoid long-term drifts.
