8. SPINDLE FUNCTIONS
(ONLY FOR Power Mate–D)
NC FUNCTION
53
Specify the spindle speed with up to five 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 of input digits for S can be specified using a parameter.
The speed of the analog interface spindle is controlled. Specify the spindle
speed with up to five digits immediately after address S. According to the
specified spindle speed, a speed command is output to the spindle motor
in a form of analog voltage. During constant surface speed control, an
analog voltage is output so that it matches the spindle speed reached after
constant surface speed control.
The speed of the serial interface spindle is controlled.
Specify the spindle speed with up to five digits immediately after address
S. A speed command is output to the spindle motor according to the
specified spindle speed. During constant surface speed control, a speed
command is output so that it matches the spindle speed reached after
constant surface speed control.
If a speed command for the spindle motor is input in a form of [sign +
12–bit binary code], the command is output to the spindle motor
according to the input.
