7.2 Spindle speed
The spindle speed is selected by program using the spindle name followed by the desired
speed. The speeds of all the spindles of the channel may be programmed in the same block.
It is not possible to program the speed of a spindle that is not in the channel.
The programmed speed stays active until another value is programmed. On power-up, after
executing an M02 or M30, and after an emergency or reset, the spindles assume a ·0· speed.
Programming format
The spindle may have any name in the S, S1...S9 range. There is no need to program the
"=" sign for the "S" spindle.
Sn={vel}
S{vel}
The speed may be programmed in rpm or in m/min (feet/min), depending on whether G197
or G196 is active. The default units are rpm.
Spindle start and stop
Defining a speed does not imply starting the spindle. The startup is defined using the
following auxiliary functions. See
"7.3 Spindle start and stop" on page 126.
M03 - Starts the spindle clockwise.
M04 - Starts the spindle counterclockwise.
M05 - Stops the spindle.
Speed ranges (gears)
Each spindle may have up to 4 different ranges (gears). Each gear means a speed range
for the CNC work in. The programmed speed must be within the active gear; otherwise, a
gear change will be required. The CNC does not admit speeds higher than the one defined
for the last gear.
The gear change may be automatic or manual. When the change is manual, the gear is
selected with auxiliary functions M41 through M44. When the change is automatic, the CNC
itself generates these functions according to the programmed speed. See
"7.4 Gear
change." on page 128.
