B-63950EN/02 4.DESCRIPTION OF PARAMETERS
- 187 -
# 4 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.
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.
# 5 NSF For the M series, when a T type gear is selected (with bit 4 (GTT) of
parameter No. 3706 set to 1 or with the option for constant surface
speed control), and an S code is specified:
0: SF is output.
1: SF is not output.
NOTE
This parameter does not affect S code output. For
an S command for maximum spindle speed
clamping (G92S-- - ;), SF is not output, regardless
of the setting of this parameter.
# 6 SFA The SF signal is output:
0: When gears are switched.
1: Irrespective of whether gears are switched.
#7 #6 #5 #4 #3 #2 #1 #0

# 2 MPA If a spindle is to be selected using a P command (with bit 3 (MPP) of
parameter No. 3703 set to 1) in multi-spindle control, and a P
command is not specified together with an S command:
0: The alarm (PS5305) is issued.
1: The last P specified by S_ P_; (by S_ P_; specified for the path in
case of a multi-path system) is used. If P is not specified even
once after power-up, the value of parameter No. 3775 is used.
NOTE
This parameter is valid only when bit 3 (MPP) of
parameter No. 3703 is set to 1.
