This specifies the speed of the spindle motor.
The S function does not include a function for starting the spindle motor. It is effective only when the spindle has been started with
M03 or is otherwise already turning.

Description
When the spindle motor has already been started, the setting made on the PNC-3200 determines whether operation is performed
simultaneously with specification or after completion of the block in which the specification is made. If specified when the spindle
motor is stopped, the speed specified by the S function is enabled when M03 is given.
A numerical value for the speed is specified following S. The rotation speed may be specified as rpm or through the speed code specifi-
cation. The number input by the operator will be interpreted by the system depending on the setting in the PNC-3200 display (refer to
the “User's Manual 3 Cutting Using NC-Codes” for information on setting this).
Specifying the speed (in rpm)
This method specifies the speed in units of rpm (revolutions per minute).
If the specified speed exceeds the maximum speed, the maximum speed is set. Similarly, the minimum speed is set if the specified
speed is less than the minimum speed.
Numerical code specification
With this method, speeds are pre-assigned to numerical codes from 01 to 99, and these numerical codes are specified to set the desired
speed.
If the specified speed exceeds the maximum speed, the maximum speed is set. Similarly, the minimum speed is set if the specified
speed is less than the minimum speed.
If a value of 0 (zero) is specified, the minimum speed is set.
If a real number is specified, any value to the right of the decimal point is truncated.
The speeds assigned to the numerical codes are shown in the table on the following page.
