Device Control

The starting and stopping of the drive and several mode specific commands are executed by the state machine.

Modes of Operation

The operation mode defines the behavior of the drive. The following modes are defined in this profile:

Homing Mode

This chapter describes the various methods to find a home position (also: reference point, datum, zero point).

Profile Position Mode

The positioning of the drive is defined in this mode. Speed, position and acceleration can be limited and profiled moves using a Trajectory Generator are possible as well.

Profile Velocity Mode

The Profile Velocity Mode is used to control the velocity of the drive with no special regard of the position. It supplies limit functions and trajectory generation.
