Brief description
For the display and processing of the technology object's position, the decisive factor is
whether the position is represented as a unit of length (linear axis) or as a rotary unit (rotary
axis).
Examples of units of length: mm, m, km
Examples of rotary units: °, rad
For the determination of the physical position from an actual encoder value, the system must
know the various properties and configurations of the mechanics.
Positioning axis/synchronous axis
The following configuration options for mechanics are supported:
● Load gear
● Leadscrew pitch (linear axes only)
● Type of encoder mounting:
– On the motor side (before the load gear)
– On the load side (after the load gear and as applicable the leadscrew)
– External (e.g. odometer)
● Inversion of the setpoint
● Inversion of the setpoint
External encoder
The following configuration options for mechanics are supported:
● Measuring gearbox (for rotary encoders)
● Leadscrew (only with linear system of units and rotatory encoders)
● Inversion of the setpoint
Speed axis
The following configuration options for mechanics are supported:
● Load gear
● Inversion of the setpoint
