B–63090EN/02

RSC In the constant surface speed control mode, the surface speed of a rapid
traverse block is calculated:
0 : In accordance with the coordinates of the end point.
1 : In accordance with the current value, as in cutting feed.
MSI In multi–spindle control, the SIND signal is valid
0 : Only when the first spindle is valid (SIND signal for the 2nd, 3rd
spindle becomes ineffective)
1 : For each spindle irrespective of whether the spindle is selected (Each
spindle has its own SIND signal).
MRS When the S 12–bit code signals and actual spindle speed signals are
output in multi–spindle control:
0: Signals common to the first and second spindles are used. In this case,
information about a spindle selected by the spindle selection signal
(SWS1–SWS3<G027#0–#2>) and SWS4<G026#3>) is output.
1: Information about each of the first and second spindles is output on
individual signals.
Signal When MRS is set to 0 When MRS is set to 1
S 12–bit code signals
R01O–R12O<F036,F037>
Actual spindle speed signals
AR0–AR15<F040,F041>
First spindle (SWS1 = 1)
Second spindle (SWS1 = 0, SWS2 = 1)
First spindle
S 12–bit code signals 2
R01O2–R12O2<F200,F201>
Actual spindle speed signals 2
AR200–AR215<F202,F203>
– Second spindle
NOTE
1 To use this parameter, the multi–spindle control option and
serial spindle option are required.
2 To use the actual spindle speed signals, the actual spindle
speed output option is required.
SMC The function to check a large S command is:
0 : Not used.
1 : Used.
If a spindle gear of M type is selected, this function compares the specified
S value and the settings of parameters No. 3741 to No. 3743 and raises an
alarm if the S value is greater.
If this function is used, specifying an S value larger than the settings of
parameters No. 3741 to No. 3743 causes P/S alarm 5310 to be raised.
NOTE
This function cannot be used together with any of bit 4
(GTT) of parameter No. 3706, constant surface speed
control, or multi–spindle control.
