MDS-D2/DH2 Series Instruction Manual
2.8 Peripheral Control Wiring
bit 4 : Designate zero point return
0: Automatically return to zero point before synchronous tapping is started (tapping phase
alignment)
1: Not return to zero point and immediately synchronous tapping is started
bit 3 :
Not used. Set to "0".
bit 2-1 : Orientation direction
bit 2,1=
00: Short-cut
01: Forward run
10: Reverse run
bit 0 : Z phase detection direction
0: Forward direction 1: Reverse direction
【#3108】 ori_sft Position shift amount for orientation
The orientation stop position can be moved with this parameter setting although normally the
position is Z -phase position. During multi-point orientation control, the stop position is determined by
the total value of this parameter and the position data for multi-point orientation of PLC input.
---Setting range---
-35999 to 35999 (0.01°)
【#3109】 zdetspd Z phase detection speed
For the first S command after power is turned ON, the spindle rotates at the speed of setting value
for this parameter.
When "#3106/bitF = 1" (Spindle zero point proximity switch detection enabled), also proximity switch
is detected.
(Note) When spindle zero point return proximity switch detection is enabled, the rotation direction of
the orientation/zero point return (synchronous tapping, spindle/C axis, etc.) will follow Z phase
detection direction. And the speed will follow Z phase detection speed (In order to prevent the
influences of the delayed detection of the signal pulse edges).
【#13225】 SP225 SFNC5 Spindle function 5
bit 5 : ddir Proximity switch signal enable edge
0: Falling edge 1: Rising edge
【#13227】 SP227 SFNC7 Spindle function 7
bit F-C : dis Digital signal input selection
0: No signal
1: SLS (Safely Limited Speed) function door state signal
4: Proximity switch signal detection
Other settings: setting prohibited

Control input 5 bitD. Zero point re-detection request (ORC)
When ORC is changed from 0 to 1, the Z phase passed will be 0(control output2/bit0).
Control output 5 bitD. Zero point re-detection complete (ORF)
If the zero point re-detection is completed after the zero point re-detection request (control input5/bitD) is set to1,
ORF=1 is set. If the zero point re-detection request is set to 0, ORF=0 is set.
