Coolant, Feed Rate and Spindle Variables

The $COOLDEV Variable

$\textbf{{\char36}COOLDEV}$

Auxiliary COOLNT device status (–1:NA, 0:OFF, 1:ON)

Type: Numeric, Read/Write

The $COOLDEV variable is an array containing the status of 9 auxiliary coolant devices, where a value of –1 indicates an unknown state or unsupported device, 0 indicates the coolant device is OFF and 1 indicates the device is ON.

The $COOLNT Variable

$\textbf{{\char36}COOLNT}$

Primary COOLNT status name (OFF, FLOOD, MIST…)

Type: Minor Word, Major Word or Sequence, Read/Write

The $COOLNT variable contains the current primary coolant status in the form of a minor word, a major word or a sequence of minor and/or major words. It will be one of the values: OFF, FLOOD, MIST, TAPKUL, THRU or a custom coolant keyword or sequence of keywords as defined in QUEST.

The $COOLTYP Variable

$\textbf{{\char36}COOLTYP}$

Primary COOLNT status type (0:OFF, 1:FLOOD, 2:MIST…)

Type: Numeric, Read/Write

The $COOLTYP variable contains the current primary coolant status in the form of a number. It has a value of 0 for OFF, 1:FLOOD, 2:MIST, 3:TAPKUL, 4:THRU or the values 5-9 for custom coolant types.

The $F Variable

$\textbf{{\char36}F}$

Current feed rate in the current mode

Type: Numeric, Read/Write

The $F variable contains the current feed rate in the current mode of operation.

The $FMODE Variable

$\textbf{{\char36}FMODE}$

Feed rate mode. (–1:? 0:uPM 1:uPR 2:inverse time)

Type: Numeric, Read/Write

The $FMODE variable contains the current feed rate mode. If the value is –1 then the mode is currently unknown. Setting this variable changes the output feed rate mode, it does not change the input feed rate mode and units specified in the CL file.

The $HPCOOL Variable

$\textbf{{\char36}HPCOOL}$

High pressure coolant status (–1:NA, 0:OFF, 1:ON)

Type: Numeric, Read/Write

The $HPCOOL variable contains the state of the high pressure coolant pump. It has a value of –1:unknown state or unsupported device, 0:OFF and 1:ON.

The $MAXPRSSUR Variable

$\textbf{{\char36}MAXPRSSUR}$

Maximum coolant pressure (0:NA)

Type: Numeric, Read/Write

The $MAXPRSSUR variable sets the maximum permitted coolant pressure in the units of pressure as defined in QUEST. This limits the pressure that can be defined via the COOLNT/PRSSUR command. Set this variable to 0 (zero) to reset the maximum pressure to the device upper limit as defined in QUEST.

The $MAXRPM Variable

$\textbf{{\char36}MAXRPM}$

Current maximum RPM setting

Type: Numeric, Read/Write

The $MAXRPM variable contains the current spindle speed maximum revolutions per minute. Setting $MAXRPM will override the maximum RPM for the current gear and spindle, but will not output NC codes to set the maximum RPM at the machine. Use the SPINDL/MAXRPM command to both set the maximum and output appropriate NC codes.

The $PRSSUR Variable

$\textbf{{\char36}PRSSUR}$

Current coolant pressure

Type: Numeric, Read/Write

The $PRSSUR variable contains the current coolant pressure in the units of pressure as defined in QUEST.

The $S Variable

$\textbf{{\char36}S}$

Current spindle speed in the current mode

Type: Numeric, Read/Write

The $S variable contains the current spindle speed in the current mode of operation. If the spindle is off then the value will be zero (0). Setting $S sets both $SR and $SS.

The $SDIR Variable

$\textbf{{\char36}SDIR}$

Spindle direction. (0:? 1:CLW 2:CCLW)

Type: Numeric, Read/Write

The $SDIR variable contains the current spindle direction. If the value is zero, then the direction is unknown. Setting this variable to zero does not stop the spindle.

The $SGMAX Variable

$\textbf{{\char36}SGMAX}\textbf{(}\mathit{gear}\textbf{)}$

Spindle gear maximum.

Type: Numeric, Read-only

The $SGMAX array contains the maximum spindle speed for each gear, in the form $SGMAX(gear). A value of 0 (zero) is returned if the gear is not defined. A maximum of 10 gears are supported.

The $SGMIN Variable

$\textbf{{\char36}SGMIN}\textbf{(}\mathit{gear}\textbf{)}$

Spindle gear minimum.

Type: Numeric, Read-only

the $SGMIN array contains the minimum spindle speed for each gear, in the form $SGMIN(gear). A value of 0 (zero) is returned if the gear is not defined. A maximum of 10 gears are supported.

The $SMODE Variable

$\textbf{{\char36}SMODE}$

Spindle mode. (0:Off 1:SFM 2:RPM 3:SMM)

Type: Numeric, Read/Write

The $SMODE variable contains the current spindle mode. Setting this variable to a non zero value sets the current output mode. Set it to zero to indicate a stopped spindle.

The $SR Variable

$\textbf{{\char36}SR}$

Current spindle speed in RPM

Type: Numeric, Read/Write

The $SR variable contains the current spindle speed in revolutions per minute. If the spindle is off then the value will be zero (0).

The $SRANGE Variable

$\textbf{{\char36}SRANGE}$

Current spindle gear number. (–1:?, 1-10:gear number)

Type: Numeric, Read/Write

The $SRANGE variable contains the current gear number specified by the range option of the SPINDL command. Set the range to –1 to force a range change with the next SPINDL command.

The $SS Variable

$\textbf{{\char36}SS}$

Current spindle speed in SFM or SMM

Type: Numeric, Read/Write

The $SS variable contains the current spindle speed in surface feet per minute or surface meters per minute. If the spindle is off then the value will be zero (0).
