【#3108】 ori_sft Position shift amount for orientation
The orientation stop position can be moved by 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 until Z phase is detected twice.
When "#3106/bitF = 1" (Spindle zero point proximity switch detection enabled), also proximity switch
is detected.
(Note) When spindle zero point proximity switch detection is enabled, the rotation direction of the
---Setting range---
1 to 99999 (r/min)
【#3110】 tap_spd Synchronous tapping zero point return speed
Set the zero point return speed during synchronous tapping control.
---Setting range---
1 to 99999 (r/min)
【#3111】 tap_sft Synchronous tapping zero point return shift amount
Set the zero point return shift amount during synchronous tapping control. Zero point angle shifts
from Z phase according to the setting angle.
---Setting range---
0 to 35999 (0.01°)
【#3112】 cax_spd Spindle C axis zero point return speed
Set the zero point return speed during spindle C axis control.
---Setting range---
1 to 99999 (r/min)
【#3113】 cax_sft Spindle C axis zero point return shift amount
Set the spindle C axis zero point return shift amount. Zero point angle shifts from Z phase according
to the setting angle.
---Setting range---
0 to 359999 (0.001°)
【#3114】 cax_para_chg
Not used. Set to "0".
【#3115】 sp2_t1 Time constant in orientation/position loop reference position return (Gear:
00)
Set the acceleration/deceleration time constant to reach the spindle's limit speed (slimt), when
spindle rotates in orientation/position loop zero point return method (C axis, tapping) using gear 00
(Linear acceleration/deceleration pattern).
(Note 1) Set a value that is bigger than the values set by "#3101 sp_t1 to #3104 sp_t4".
(Note 2) If you set this parameter to "0" by SRAM clear, etc., the time constant is equivalent to "1ms".
---Setting range---
0 to 30000 (ms)
orientation/zero point return (synchronous tapping, spindle/C axis) will follow Z phase detection
direction. And the speed will follow Z phase detection speed.
If this parameter is set to an illegal value, this parameter follows the settings of "sp_t1 to sp_t4".
