(3) Detection signal polarity
The table below is the polarities of the detections signals. According to the polarity, select the enable edge of the
signals with the spindle parameter (SP225/bit5).

(4) Parameter setting
When using the proximity switch, set the following parameters to the spindle to be used.
When the proximity switch detection is enabled, the rotation direction of the orientation follows Z-phase detection
direction (#3106/bit0), and the rotation speed follows Z-phase detection speed (#3109).
【#3106】 zrn_typ Zero point return specifications
Select the zero point return specification.
bit F : Spindle zero point detection with contactless switch
0: Normal
1: Enable spindle zero point detection using proximity switch
bit E : Control mode selection in orientation
Select non-interpolation mode when vibration occurs since the gain is high during the orientation.
0: Interpolation mode (Use the interpolation mode gain "SP002".)
1: Non-interpolation mode (Use the non-interpolation mode gain "SP001")
bit D : Interpolation mode selection 1 (zero point return initiated during rotation)
0: Non-interpolation mode
1: Interpolation mode
bit C : Z phase detection method
0: Follows Z phase detection direction (bit0).
1: Rotates in the commanded direction at Z phase detection speed to detect Z phase.
* To enable Z phase detection operation, set the parameter "#3106 zrn_typ bit3 (Z phase detection
