Origin Search Operation
Mode 2
158
Note During error counter reset output, if the origin input signal turns ON again, the
Servo Drive's error counter reset function is deemed to have been used, and
the error counter reset output is turned OFF. In this case, the output time of
the error reset counter will be less than 20 ms.
Origin Detection Method: 0
When the deceleration time is short, such as in cases where positioning
begins from within the origin proximity area, an origin input signal will be
detected immediately after the falling edge of the origin proximity input signal.
Be sure that the origin proximity input signal dog is long enough (i.e., more
than the deceleration time).

Origin Detection Method: 1
If an origin proximity input signal is input during deceleration, the stop position
will vary according to the length of the deceleration time.

This mode is similar to mode 1, except that the positioning completed input
signal (INP) is also used. The positioning completed input signal from the
Servo Drive is connected to the positioning completed input of the PCU's
external I/O connector.
