4. DESCRIPTION OF PARAMETERS
171
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.

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.
0 : Confirmation of SAR is necessary.
1 : Confirmation of SAR is unnecessary.
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.
Set value=
× 1000
Measured data (V)
10 (V)
(5) After setting the parameter, specify the spindle speed so that the
analog output of the spindle speed is the maximum voltage. Confirm
that the output voltage is 10V.
NOTE
This parameter needs not to be set for serial spindles.
