Description
Set the detail of the touch probe function.
By setting [Pr. PT26.4 Touch probe latch position selection], the reflecting patterns of [Pr. PA14 Travel direction selection] and
[Pr. PT08 Homing position data] to the latched position feedback can be changed.
When the touch probe function is not available for the servo amplifier being used, set "0000h".
Bit
Description
0
0: Touch probe 3 disabled
1: Touch probe 3 enabled
1
0: Single trigger mode
1: Continuous trigger mode
2
0: Triggered by inputting touch probe 3
1: Triggered at the zero point of the encoder
3
(reserved) The value at reading is undefined. Set "0" when writing.
4
0: Stop sampling the rising edge of touch probe 3
1: Start sampling the rising edge of touch probe 3
If input of touch probe 3 is set as a trigger (bit 2 = 0), the position feedback latched at the rising edge of touch probe 3 is stored in [Touch
probe 3 positive edge (Obj. 2DEAh)], and the time stamp in [Touch probe time stamp 3 positive value (Obj. 2DF8h)].
If the zero point of the encoder is set as a trigger (bit 2 = 1), the position feedback at passing the zero point of the encoder
[Touch probe 3 positive edge (Obj. 2DEAh)].
5
0: Stop sampling the falling edge of touch probe 3
1: Start sampling the falling edge of touch probe 3
If input of touch probe 3 is set as a trigger (bit 2 = 0), the position feedback latched at the falling edge of touch probe 3 is stored in [Touch
probe 3 negative edge (Obj. 2DEBh)], and the time stamp in [Touch probe time stamp 3 negative value (Obj. 2DF9h)].
If the zero point of the encoder is set as a trigger (bit 2 = 1), the position feedback at passing the zero point of the encoder
[Touch probe 3 negative edge (Obj. 2DEBh)].
6
(reserved) The value at reading is undefined. Set "0" when writing.

*1 For linear servo motors, the zero point of the encoder is a position between homing stop intervals [pulse] (changeable with [Pr. PL01.2
Homing stop interval setting]) based on the linear encoder home position.
