3705 EVS ESF
(Bit)#7 #6 #5 #4 #3 #2 #1 #0
Data type: Bit
ESF: When the spindle control function (S analog module) is used:
0 : S codes and SF are output for all S commands.
1 : S codes and SF are not output for an S command in
constant surface speed control mode (G96 mode) or
maximum spindle speed clamp command (G50 when G
code system A is used).
NOTE
This bit (ESF) is enabled, when bit 5 (NSF) of parameter
No.3705 is set to 1
EVS When the spindle control function (Spindle analog output or
Spindle serial output) is used, S codes and SF are:
0 : Not output for an S command.
1 : Output for an S command.
NOTE
The output of S codes and SF for an S command in constant
surface speed control mode (G96), or for an S command
used to specify maximum spindle speed clamping
(G50S–––;) depends on the setting of bit 0 (ESF) of
parameter No.3705.
