- 295 -
3850 Upper limit of spindle speed of the fourth spindle
[Data type] 2-word
[Unit of data] min
-1
[Valid data range] 0 to 32767
Set the upper limit of spindle speed of the fourth spindle.
NOTE
1 This parameter is valid when the multi-spindle
control option is selected.
2 For this parameter to be valid with the M series, the
multi-spindle control option needs to be selected,
and the constant surface speed control option
needs to be selected, or bit 4 (GTT) of parameter
No. 3706 needs to be set to 1. (This setting is
required to enable multi-spindle control with the M
series.)
3 When the constant surface speed control option is
selected, the spindle speed is clamped to a
maximum speed, regardless of whether the G96
mode or G97 mode is set.
4 When this parameter is set to 0, parameter No.
3772 (maximum speed of the first spindle) is valid.
The spindle speed is not clamped when parameter
No. 3772 is set to 0.
5 When spindle speed command control is applied
using the PMC, this parameter has no effect, and
the spindle speed is not clamped.
6 This parameter is valid just for Series 16i/160i/160is.
