Origin Search Operation
The origin search operation is completed when the rising edge of the Origin
Proximity Input Signal is detected and then the rising edge of the Origin Input
Signal is detected.
Example PLC Setup Settings
Operating Mode 1 Connection Example
In operating mode 1, the Error Counter Reset Output is turned ON when the
origin location is determined by detection of the rising edge of the Origin Input
Signal.
In this example, a servo driver is used and the encoder's phase-Z output is
used as the Origin Input Signal terminal. The servo driver is an OMRON W-
series Servo Driver.
