In each control cycle (1 ms), the profile generator calculates position, speed, and acceleration required to do the specified move-
ment. The outputs from the profile generator are used for the position and speed controller.
6.2.2 Homing
Homing is required for creating a reference to the physical machine position in closed-loop control principle with incremental en-
coder or in sensorless control principle. IMC supports various homing functions with or without a homing sensor. Select the homing
function in parameter 17-80 Homing Function. After selecting a homing function, complete homing before executing absolute posi-
tioning.
6.2.3 Synchronization
In synchronization mode, the drive follows the position of a master signal. The master signal and the offset between the master and
the slave are handled as shown in
