SAM
[Data type] Bit
SAM The sampling frequency to obtain the average spindle speed
0 : 4 (Normally, set to 0.)
1 : 1
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 Actual spindle speed signals and S 12–bit code signals to be output when
multi–spindle control is performed
0 : Signals common to the first and second spindles are used, and the signals
for the spindle selected by the spindle selection signal are output.
1 : Separate signals are output to the first and second spindles.
Signal When MRS is 0 When MRS is 1
Actual spindle speed signals AR0 to
AR15 (F040, F041)

NSAx
[Data type] Bit axis
NSAx This parameter specifies an axis for which confirmation of the spindle
speed reached signal (SAR) is unnecessary when a move command is
executed for the axis. When a move command is issued only for an axis
for which 1 is set in this parameter, the spindle speed reached signal
(SAR) is not checked.
3730 Data used for adjusting the gain of the analog output of spindle speed
[Data type] Word
[Unit of data] 0.1 %
[Valid data range] 700 to 1250
Set data used for adjusting the gain of the analog output of spindle speed.
[Adjustment method]
(1) Assign standard value 1000 to the parameter.
(2) Specify the spindle speed so that the analog output of the spindle
speed is the maximum voltage (10 V).
(3) Measure the output voltage.
(4) Assign the value obtained by the following equation to parameter
No.3730.
