MC_Home: Home technology objects, set home position V1

Description
With the Motion Control instruction "MC_Home", you create the relationship between the
position in the technology object and the mechanical position. The position value in the
technology object is assigned to a homing mark at the same time. This homing mark
represents a known mechanical position.
The homing process occurs according to the mode selected with the "HomingMode"
parameter, and the configuration under "Technology object > Configuration > Extended
parameters > Homing".
The preset values under "Technology object > Configuration > Extended parameters >
Dynamic default values" are used for the dynamic values Acceleration, Deceleration and
Jerk.
Applies to
● Positioning axis
● External encoder
The following table shows which modes are possible with each of the technology objects:
Operating mode
Active homing
(HomingMode = 4, 5)
Passive homing
(HomingMode = 2, 3, 8)
Setting a positioning
value
("HomingMode" = 0)
Relative shift of the
actual value
("HomingMode" = 1)
Homing absolute en-
coder
("HomingMode" = 6, 7)
