II - 92
【#3104】 sp_t 4 Time constant for spindle rotation with S command (Gear: 11)
Set the acceleration/deceleration time constant for a spindle when the spindle is rotated by
an S command (spindle control mode = speed operation mode) using gear11 (Linear
acceleration/deceleration pattern).
This parameter is also used to set the time constant for the spindle rotation when the Z-
phase is detected.
(Note) If you set this parameter to "0" by SRAM clear, etc., the time constant is equivalent to
"1ms".
---Setting range---
0 to 30000 (ms)
【#3105】 sut Speed reach range
Set the speed deviation rate with respect to the commanded speed, at which the speed
reach signal will be output.
It will be 15% when set to "0".
If the speed deviation is smaller than 45r/min, it will be set as 45r/min.
---Setting range---
0 to 100 (%)
【#3106】 zrn_typ Zero point return specifications
Select the zero point return specification.
Functions are allocated to each bit.
Set this in hexadecimal format.
bit F : Spindle zero point detection with contactless switch
0: Normal 1: Enable spindle zero point detection using proximity switch
bit E : Interpolation mode selection in orientation
0: Interpolation mode (Use the interpolation mode gain "SP002 PGN".)
1: Non-interpolation mode (Use the non-interpolation mode gain "SP001 PGV")
Select this when vibration occurs since the gain is too high during the orientation.
bit D-B :
Not used. Set to "0".
bit A-9 : Spindle/C axis zero point return direction
00: Short-cut 01: Forward run 10: Reverse run 11: Reverse run
bit 8 : Designate zero point return/deceleration stop of spindle/C axis
0: Zero point return 1: Deceleration stop
bit 7 : Synchronous tapping command polarity
0: Forward direction 1: Reverse direction
bit 6-5 : Synchronous tapping zero point return direction
00: Short-cut 01: Forward run 10: Reverse run 11: Reverse run
bit 4 : Designate zero point return/deceleration stop in synchronous tapping
0: Zero point return; a start position in synchronous tapping is adjusted to "#3111 tap_sft
(Synchronous tapping zero point return shift amount)". (Use this setting when the
tapping start position needs to be adjusted.)
1: Deceleration stop; tapping starts from the position where the synchronous tap is
commanded.
bit 3 :
Not used. Set to "0".
bit 2-1 : Orientation direction
00: Short-cut 01: Forward run 10: Reverse run 11: Reverse run
bit 0 : Z phase detection direction
0: Forward direction 1: Reverse direction
【#3107】 ori_spd Orientation command speed
Set the spindle speed during orientation command.
When the spindle is not running or running to the different direction with the orientation, the
orientation is carried out with this speed after a stop. When the spindle is running to the
same direction with the orientation, this parameter does not have a meaning because it
decelerates directly and the orientation is carried out.
