• Homing
Homing establishes the home position measurement in the converter to the machine.
Possible homing types are:
– Active homing
– Passive homing
– Absolute encoder adjustment
• Traversing blocks
Position, velocity, and acceleration are saved in different traversing blocks in the converter.
The external control selects a traversing block.
• Direct setpoint input (MDI)
The external control specifies the setpoints (position, velocity, and acceleration) for the axis.
• Jogging
This function is used to incrementally traverse the axis (for example, for setting up).

Axis type
Overview
Axes in your actual application can be configured with different motion control applications:
• For speed control applications: flexible control of the speed and direction of rotation of rotary
axes
• For positioning control applications: relative/absolute positioning of rotary or linear axes
(depending on mechanics)
Description of function
Linear axis
A linear axis is an axis whose traversing range is limited in both motor directions of rotation
by the mechanical system of the machine, for example:
• Stacker crane
• Elevating platform
• Tilting station
• Gate/door drive
