- 118 -
9.1 S CODE OUTPUT
Specify the spindle speed with up to ten digits immediately after
address S. The 5-digit numeric value is output to the PMC as a 32-bit
binary code.
The code is maintained until another S is specified. The maximum
number and sign (minus) of input digits for S can be specified using a
parameter.
9.2 SPINDLE SPEED BYNARY OUTPUT
A specified spindle speed is output to the PMC as a 16-bit binary code.
Under constant surface speed control, a spindle speed after constant
surface speed control has been exercised is output. If constant surface
speed control is not used, this code is held until the next S code is
specified.
9.3 SPINDLE SPEED ANALOG OUTPUT
The speed of the analog interface spindle is controlled.
When an output voltage for the spindle motor is entered using [sign +
13 bits], the corresponding analog voltage can be output.
Maximum output voltage ±10V
9.4 SPINDLE SPEED SERIAL OUTPUT
The speed of the serial interface spindle is controlled.
If a speed command for the spindle motor is input in a form of [sign +
13-bit binary code], the command is output to the spindle motor
according to the input.
