Operating instructions

04/08 Application manual Positioning 135
A: Homing direction (search direction) is anticlockwise toward negative HW limit
switch if home switch and limit switch are inactive. The home switch is in search
direction. Travel to left edge of home switch is performed at
Fast Speed 1132.
When the home switch is passed, the direction of rotation is reversed. Home position
is the first encoder ref. signal after travel in positive direction. Search for the home
position is performed at
Creep Speed 1133
B: When homing is started, the home switch is active. Homing direction (search
direction) is anticlockwise toward negative HW limit switch. Travel to left edge of
home switch is performed at
Fast Speed 1132. When the home switch is passed in
negative direction, the direction of rotation is reversed. Home position is the first
encoder ref. signal after traveling in positive direction. Homing is performed at
Creep Speed 1133.
C: Homing direction (search direction) is anticlockwise toward negative HW limit
switch. The home switch is not in search direction. The positive limit switch acts as a
reversing switch. When the negative limit switch is reached, the direction of rotation
is reversed, and homing is performed in positive direction. Home position is the first
encoder ref. signal after the home switch is reached. During the whole operation,
homing is performed at
Fast Speed 1132.
