6 Integrated Motion Controller
6.1 Introduction
N O T I C E
The integrated motion control is only available with special IMC software version 48.XX. To order the drive with the IMC software,
use the type code with software release version S067.
The integrated motion controller (IMC) enables position control with all motor control principles and motor types with and without
feedback.
To activate the IMC functionality, select [9] Positioning or [10] Synchronization in parameter 1-00 Configuration Mode. IMC enables the
following functions:
Positioning: Absolute, relative, and touch probe.
Homing.
Position synchronization.
Virtual master.
Position control in both positioning and synchronization modes can be either sensorless or with feedback. In the sensorless control
principle, the motor angle calculated by the motor controller is used as feedback. In the closed-loop control principle, VLT

Automa-
tionDrive FC 301 supports 24 V encoders as standard. With extra options, the drive supports most standard incremental encoders,
absolute encoders, and resolvers. The position controller can handle both linear and rotary systems. The controller can scale posi-
tions to any relevant physical unit such as mm or degrees.
6.2 Positioning, Homing, and Synchronization
6.2.1 Positioning
The drive supports relative positioning and absolute positioning. A positioning command requires 3 inputs:
Target position.
Speed reference.
Ramp times.
The 3 inputs can come from various sources, see Illustration 100.
