16 Machine Parameters
#43048 smax_tap3
Specify the maximum rotation speed in synchronous tapping multi-step acceleration/deceleration control
when gear 10 is selected.
Inclination of 3rd linear acceleration/deceleration control is determined by the ratio of smax_tap3(#43048)
and tapt33(#3047).
When 0 is set to smax_tap3, use smax3(#3007).
When smax_tap3 is smax3 or more, use smax3.
---Setting range---
0 to 99999 (r/min)
#43049 smax_tap4
Specify the maximum rotation speed in synchronous tapping multi-step acceleration/deceleration control
when gear 11 is selected.
Inclination of 3rd linear acceleration/deceleration control is determined by the ratio of smax_tap4(#43049)
and tapt34(#3048).
When 0 is set to smax_tap4, use smax4(#3008).
When smax_tap4 is smax4 or more, use smax4.
---Setting range---
0 to 99999 (r/min)
#43070 loadrate_warn
[M8]
Specify the equivalent load factor of the spindle motor that causes the warning at the start of automatic op-
eration.
The warning appears when the equivalent load factor has exceeded the specified value.
0: Disable the warning
1 to 200: Warning display threshold [%]
[C80]
Not used.
#43071 sp_spd_flc_dtc_p
[M8]
This parameter is used when address P is omitted from the spindle speed fluctuation detection command
(G162).
Specify a length of delay time from when G162 command is given to when the control detects a fluctuation.
This delay time is also applied to a change in spindle speed command. A change in spindle speed command
means a difference in the final command given to the spindle drive unit.
---Setting range---
0 to 99.999 (s)
[C80]
Not used.
#43072 sp_spd_flc_dtc_r
[M8]
Specify the allowable spindle speed fluctuation rate to be applied to the spindle speed fluctuation detection
command (G162) from which address R is omitted.
When "0" is set, the allowable rate is 15%.
If a speed deviation with respect to the command speed is smaller than 45 r/min, the speed deviation is treat-
ed as 45 r/min.
---Setting range---
0 to 100 (%)
[C80]
Not used.
