7.5.10 Wait on Input – M66
NOTE: These commands are only useful when the mill is equipped with the USB I/O Module (PN 32616).
There are four digital inputs available on the USB I/O module.
M66 P- | E- <L->
Word Definition
P- Species the digital input number from 0 to 3.
L-
Species the wait mode type:
• Mode 0: IMMEDIATE – no waing, returns immediately. The value of the input at that
me is stored in parameter #5399.
• Mode 1: RISE – waits for the selected input to perform a rise event.
• Mode 2: FALL – waits for the selected input to perform a fall event.
• Mode 3: HIGH – waits for the selected input to go to the HIGH state.
• Mode 4: LOW – waits for the selected input to go to the LOW state.
Q-
Species the meout in seconds for waing. The Q value is ignored if the L-word is zero
(IMMEDIATE). A Q value of zero is an error if the L-word is non-zero.
7.6 Other Input Codes
7.6.1 Feed Rate – F
To set the feed rate, program: F~
Depending on the seng of the feed mode toggle, the rate may be in units-per-minute or units-per-
rev of the spindle. The units are those dened by the G20/G21 mode. The feed rate may somemes
be overridden as described in M48 and M49 above.
7.6.2 Spindle Speed – S
To set the speed in revoluons per minute (rpm) of the spindle, program: S~
The spindle turns at the commanded speed when it has been programmed to start turning. It is OK
to program an S word whether the spindle is turning or not. If the speed override switch is enabled
and not set at 100 percent, the speed is dierent from what is programmed. It is OK to program S0,
but the spindle does turn if that is done. It is an error if:
• The S number is negave
