The stop position is the same in Mode 1 and Mode 2. For an operation where the
start location of the origin search is different or where the deceleration time is
short, refer to the previously-described Mode 1. In Mode 3, if deceleration is not
completed when the origin proximity input signal is turned ON and then turned
OFF, an origin adjustment signal will be output after deceleration is completed.
Origin Detection Method: 1
Deceleration starts on the rising edge of the origin proximity input signal, and an
origin adjustment command is output when deceleration is completed.
