Origin Return - Fuji Electric Faldic-a RYS-R Series User Manual

■ Related items
(1) Parameter setting
Origin return action depends on basic para. setting.
Basic parameter 72 to 78
Para. Name
72 Origin return direction
73 Z-phase detection valid/invalid
74 Origin LS logic
75 Origin return speed
76 Origin detection creep speed
77 Origin shift quantity
78 2nd origin
After the setting change of the basic para. 71, 72, and 78, power supply need be turned on again.
(2) Origin return action
At the ON edge of [ORG] signal, the following operations are automatically carried out.
(a) At the ON edge of [ORG] signal, motor rotation start at the origin return speed (basic para. 75) in the origin return direction (basic para.
72).
(b) When the [LS] signal turns from off to on, speed is reduced to the origin detection creep speed (basic para. 76). While [LS] on, motor runs
at constant speed.
(c) The first Z-phase signal is detected, following the transfer point of [LS] signal from OFF edge to ON edge.
(d) The motor stops after rotating by the origin shift quantity (basic para. 77) from the detection of Z-phase signal.
(e) The indexing end [WPSET] signal turns on, with the stopped position as the No.1 station number. The origin return end signal as the
control output signal turns on.
With the Z-phase input invalid selected in the Z-phase valid/invalid (basic para. 73), motor can be stopped after running by the origin shift
quantity from the ON edge to OFF edge of [LS] signal.
The on/off status of [LS] signal can be inverted using the origin LS logic (basic para. 74).

■ Origin return

At the ON edge of [ORG] signal, the aforementioned operations (a) through (e) are carried out.
The origin return action can be carried out again, regardless of the on/off status of the origin return end signal.
