Operation
The following PTP parameter settings are related to origin search. Make the settings according to the
mechanical system.
Note 1. The acceleration and deceleration times for origin search will be acceleration time 0 (PP-20)
Note 2. The direction of movement for origin search is determined by the origin search direction
Note 3. When origin compensation (PP-06, PP-07) is set, positioning moves for just the set amount

The operation sequences for the three origin search patterns are shown below.
For these examples it is assumed that the factory settings are used for the origin search direction
(PP-19) and the motor rotation direction (UP-26), and that origin compensation (PP-06, PP-07) is set
to “0.”
Origin search operation will start when the origin search (SEARCH) signal is turned ON, with the
READY signal ON.

second.
Specifies origin proximity search speed in
origin search operation as override value
based on reference speed. (This value is
used as axis speed for origin compensation
as well.) Set an appropriate value so that the
origin proximity signal can be detected
accurately.
Specifies phase-Z search speed in origin
search operation as override value based on
reference speed. Set an appropriate value so
that the speed will be 500 r/min maximum.
Specifies origin search direction.
0: Begin in positive (+) direction
1: Begin in negative (–) direction
Specifies number of motor sensor pulses for
movement between origin search completion
position and mechanical origin. The value can
be obtained by origin teaching.
