P Delay time or program number
The P address character is used to enter either a time in seconds or a program number for a subroutine call. If
it is used as a time (for a G04 dwell), it may be a positive decimal with fraction between 0.001 and 1000.0. If it
is used as a program name (for an M98), or a line number (for an M97), the value may be a positive number
without decimal point up to 9999.
Q Canned cycle optional data
The Q address character is used in canned cycles and is followed by a signed number in inches between 0 and
8380.000 for inches or between 0 and 83800.00 for metric.
R Canned cycle and circular optional data
The R address character is used in canned cycles and circular interpolation. It is either in inches with four
fractional positions or mm with three fractional positions. It is followed by a signed number in inches between -
15400.0000 and 15400.0000 for inches or between -39300.000 and 39300.000 for millimeters. It is usually used
to define the reference plane for canned cycles.
S Spindle speed command
The S address character is used to specify the spindle speed in conjunction with M41 and M42. The S is
followed by an unsigned number between 1 - 99999. The S command does not turn the spindle on or off; it only
sets the desired speed. If a gear change is required in order to set the commanded speed, this command will
cause a gear change to occur even if the spindle is stopped. If the spindle is running, a gear change operation
will occur and the spindle will continue running at the new speed.
T Tool selection code
The T address character is used to select the tool for the next tool change. The number following must be a
positive number between 1 and the number in Parameter 65. It does not cause the tool change operation to
occur. The Tn may be placed in the same block that starts the tool change (M6 or M16) or in any previous
block.
U Auxiliary external linear axis
The U address character is used to specify motion for the optional external linear, U, axis. It specifies a
position of motion. It is either in inches with three or four fractional positions or millimeters with three fractional
positions. It is followed by a signed number between -838.0000 and 838.0000 or -8380.000 and 8380.000 or in
millimeters between -8380.000 and 8380.000. If no decimal point is entered, the last digit is assumed to be 1/
1000 inches or 1/1000mm.
V Auxiliary external linear axis
The V address character is used to specify motion for the optional external linear, V, axis. It specifies a posi-
tion of motion. It is either in inches with three or four fractional positions or millimeters with three fractional
positions. It is followed by a signed number between -838.0000 and 838.0000 or -8380.000 and 8380.000 or in
millimeters between -8380.000 and 8380.000. If no decimal point is entered, the last digit is assumed to be 1/
1000 inches or 1/1000mm.
W Auxiliary external linear axis
The W address character is used to specify motion for the optional external linear, W, axis. It specifies a
position of motion. It is either in inches with three or four fractional positions or millimeters with three fractional
positions. It is followed by a signed number between -838.0000 and 838.0000 or -8380.000 and 8380.000 or in
millimeters between -8380.000 and 8380.000. If no decimal point is entered, the last digit is assumed to be 1/
1000 inches or 1/1000mm.
