9. SPINDLE SPEED FUNCTION
442
NOTE
1 When the constant surface speed control is selected, the
spindle speed is clamped at the maximum speed,
regardless of whether the G96 mode or G97 mode is
specified.
2 When the multi–spindle control option is selected, set the
maximum speed for each spindle in the following
parameters:
Parameter No. 3772: Sets the maximum speed for the first
spindle.
Parameter No. 3802: Sets the maximum speed for the
second spindle.
3802 Maximum speed of the second spindle
[Data type] Word
[Unit of data] min
–1
[Valid data range] 0 to 32767
Parameter sets the maximum speed for the second spindle.
When a command specifying a speed exceeding the maximum speed of
the spindle is specified, or the speed of the spindle exceeds the maximum
speed because of the spindle speed override function, the spindle speed is
clamped at the maximum speed set in the parameter.
NOTE
1 This parameter is valid when the multi–spindle control is
selected.
2 When the constant surface speed control is selected, the
spindle speed is clamped at the specified maximum speed,
regardless of whether the G96 mode or G97 mode is
specified.
3 When 0 is set in this parameter, the setting of parameter No.
3772 for the first spindle is used.
When 0 is set in parameter No. 3772, the spindle speed is
not clamped.
4 When spindle speed command control is applied using the
PMC, this parameter has no effect, and the spindle speed
is not clamped.
