Number RemarksContents
3705 Parameter for gear shift of spindle
#0 ESF : The SF signal output condition is such that S
codes and SF are output with all S commands
(0)/not output when constant surface speed
control is used or the spindle speed is clamped
(1).
#1 GST : The SOR signal is used for spindle orientation
(0)/gear shift (1)
#2 SGB : The gear switching method is method A (0)/
method B (1)
#3 SGT : The gear switching method during G84 and
G74 is method A (0)/method B (1)
#4 EVS : With an S command, S codes and SF are not
output (0)/output (1).
#5 NSF : When an S code command is issued in
constant surface-speed control, SF is output
(0)/not output (1)
#6 SFA : The SF signal is output when gears are
switched (0)/irrespective of whether gears are
switched (1)
