Origin Search and Origin Return Functions
Section 6-3
Operating Mode 1 (with Error Counter Reset Output, without Positioning
Completed Input)
Connect the phase-Z signal from the Servo Driver to the Origin Input Signal.
When the Origin Input Signal is received, the pulse output will be stopped and
the Error Counter Reset Signal will be output for about 20 to 30 ms.
When the Origin Proximity Input Signal is received, the motor will begin decel-
erating from the origin search high speed to the origin search proximity speed.
In this operating mode, the Origin Input Signal will be ignored if it is received
during this deceleration. After deceleration is completed, the Origin Input Sig-
nal will be detected and the motor will stop.
Operating Mode 1 with Origin Proximity Input Signal Reverse (Origin
Detection Method Setting = 0)
When the deceleration time is short, the Origin Input Signal can be detected
immediately after the Origin Proximity Input Signal goes from ON to OFF. Set
a Origin Proximity Input Signal dog setting that is long enough (longer than
the deceleration time.)
