Configuring
6.6 Configuring the positioning axis/synchronous axis technology object
Home position offset
In the case of a differing switch position and home position, enter the corresponding home
position offset in this field. The axis approaches the home position at approach velocity.
Home position
In this field, configure the absolute coordinate of the home position. The home position
configured here is in effect, when the Motion Control instruction "MC_Home" is executed with
Mode = 5.
Passive homing
Configuration - Passive homing
Configure the parameters for passive homing in the "Passive Homing" (homing on the fly)
configuration window. The homing function "Passive homing" is performed using the Motion
Control instruction "MC_Home" Mode = 2, 8 and 10.
Note
Parameter "MC_Home.Mode"
The "MC_Home.Mode" parameter for S7-1200 Motion Control and S7-1500 Motion Control
has been standardized within the framework of technology version V2.0. This results in a
new assignment of the parameter values for the "MC_Home.Mode" parameter. A
comparison of the "MC_Home.Mode" parameter for technology versions V1.0 and V2.0 is
available in the section Version overview (Page 86).
Selecting the homing mode
Select from among the following homing modes:
● Zero mark via PROFIdrive frame and proximity switch (Page 141)
● Zero mark via PROFIdrive frame (Page 142)
● Homing mark via digital input (Page 143)
