Group 62 Pos Correction; Homing - ABB ACSM1 Manual

Group 62 POS CORRECTION
Settings for position correction functions (homing, presets, and cyclic corrections).
With these functions, the user can define the relationship between the actual
position of the drive positioning system and the driven machinery.
Some of the correction functions need an external probe or limit switch to be
connected to the digital inputs of the drive control board or encoder interface
module.
See also section
Note: Only one position correction function can be active at a time. Homing has the
highest priority, cyclic correction the lowest.
