Operation overview
DOG method 1 Home (Z phase), based on front end The leading edge of the first home position (Z
phase) is set as a home position after the
detection of the leading edge of a near home
input (HOME).
DOG method 2 Near home input (HOME), based on
front end
The leading edge of a near home input (HOME)
is detected and it is set as a home position.
DOG method 3 Home (Z phase), based on back end The leading edge of the first home position (Z
phase) in the home return direction set as a
home position after the detection of a trailing
edge (back end) of the near home input (HOME).
DOG method 4 Near home input (HOME), based on
back end
The trailing edge (back end) of a near home input
(HOME) is detected and it is set as a home
position.
Limit method 1 Home (Z phase), based on front end Reverses after detecting the leading edge of the
limit switch on the opposite side of the home
return direction. After that, the operation stops at
the first leading edge of the home position (Z
phase). It is set as a home position.
Limit method 2 Edge detection of limit switch Detects the leading edge of the limit switch in the
home return direction and stops. It is set as a
home position.
Phase Z method Edge detection of home (Z phase) Moves the current position to the home return
direction, and stops at the position where the
leading edge of the first home position (Z phase)
is detected. It is set as a home position.
Stop-on-contact
method 1
Based on stop-on-contact Stops by a mechanical stopping mechanism as a
stopper. A position when a constant time elapses
at a torque value larger than a specified value is
set as a home position.
Stop-on-contact
method 2
Stop-on-contact + Z phase, based on
front
Although the operation is similar to the stop-on-
contact method, the first position where the Z
phase is detected is set as a home position by
performing the reverse operation after the stop by
a stopper.
Data set method - The current value is set as a home position.
