Operation mode 24: Homing to left rising edge of home switch without
encoder ref. signal with positive hardware limit switch
Pos. HW Limit Switch
A: Homing direction (search direction) is clockwise toward positive HW limit switch if
home switch and limit switch are inactive. The home switch is in search direction.
Home position is the rising edge of the home switch. During the whole operation,
homing is performed at
B: When homing is started, the home switch is active. Homing direction (search
direction) is anticlockwise toward negative HW limit switch. Travel to falling edge of
home switch signal is performed at
passed in negative direction, the direction of rotation is reversed. Home position is
the rising edge of the home switch. Homing is performed at
C: Homing direction (search direction) is clockwise toward positive HW limit switch.
The home switch is not in search direction. The positive limit switch acts as a revers-
ing switch. When the positive limit switch is reached, the direction of rotation is re-
versed, and homing is performed in negative direction. When the home switch is
passed, the direction of rotation is reversed again. At first, the operation is per-
formed at
speed is changed to
home switch.
