Resetting the "Homed" status
Incremental encoder
In the following cases, the "Homed" status is reset, and the technology object must be
rehomed.
● Errors in the sensor system / encoder failure
● Initiation of active homing with the Motion Control instruction "MC_Home" with
"Mode" = 3, 5 (after successful completion of the homing process, the status "Homed" is
set again.)
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 compariso
n of the "MC_Home.Mode" parameter for technology versions
V1.0 and V2.0 is available in the section
Version overview (Page 86).
● Initiation of passive homing with the Motion Control instruction "MC_Home" with
"Mode" = 2, 8, 10 (after successful completion of the homing process, the status "Homed"
is set again.)
● Replacement of the CPU
● Replacement of the SIMATIC Memory Card
● POWER OFF
● Memory reset
● Modification of the encoder configuration
● Restart of the technology object
● Restoration of the CPU factory settings
● Transfer of a different project into the controller
Absolute value encoder
In the following cases, the "Homed" status is reset, and the technology object must be
rehomed.
● Errors in the sensor system / encoder failure
● Replacement of the CPU
● Modification of the encoder configuration
● Restoration of the CPU factory settings
● Transfer of a different project into the controller
Resetting the memory of the CPU or upgrading a project does not require another absolute
value adjustment.
