After found the reference point, and then seek for the origin according to the second
speed of homing. Can choose forward or backward direction seeking for the Z pulse, also can
directly make the reference point as the origin.
During homing operation, in order to avoid the machinery impact caused by speed change
quickly uses the acceleration and the deceleration functions set by parameter P185, P186. The
origin position adds on the offset quantity to make the actual origin. The offset quantity is
P181×10000 + P182.

Explanation
P178 Trigger
mode of
homing
0 Closed the function of homing.
1 Voltage level triggering of terminal GOH from DI input.
2 Rising edge triggering of terminal GOH from DI input.
3 Automatic execution after turn on power supply.
P179 Reference
mode of
homing
0 After starts homing, seek REF (external detector input; rising edge
trigger) in CCW direction with first speed (P183) and take it the
reference point.
1 After starts homing, seek REF (external detector input; rising edge
trigger) in CW direction with first speed (P183) and take it the
reference point.
2 After starts homing, seek CCWL (falling edge trigger) in CCW
direction with first speed (P183) and take it the reference point.
Neglect CCWL prohibition function when homing execution, but
resume the prohibition function after the homing finished.
3 After starts homing, seek CWL (falling edge trigger) in CW
direction with first speed (P183) and take it the reference point.
Neglect CWL prohibition function when homing execution, but
resume the prohibition function after the homing finished.
4 After starts homing, seek Z pulse in CCW direction with first
speed (P183) and take it the reference point.
5 After starts homing, seek Z pulse in CW direction with first speed
(P183) and take it the reference point.
P180 Origin
mode of
homing
0 After found the reference point, seek Z pulse in backward
direction with second speed (P184) and take it the origin.
1 After found the reference point, seek Z pulse in forward direction
