12.2.3.2. Homing Phase With 1 Switch
a) 1 switch:
Figure

This homing phase is used to search for the system "switch" type stop as follows:
- First configure the switch polarity: «
High state active
" or "
Low state active
".
- Depending on the switch position (on the right or left), the user selects the appropriate "
Direction of
rotation
"
and sets a "
Homing Speed
".
- When the switch changes state, the "Switch 1" stop is detected. The motor is in the "
mechanical zero
"
position.
- To avoid the motor coming into contact with the switch each time it returns to the reference position,
"
Offset 1
"
can be set (in encoder pulses).
- This new position should be considered as the reference position. The motor positions itself at "
software
zero
": the homing phase is complete.
- As a safety measure, if the homing phase is not complete after the "
Max Homing Time
", the motor detects
a "Homing" type error and stops.
