PARAMETERS
June 1999
96-8000
Parameter 271 C SWITCHES
Parameter 271 is a collection of single-bit flags used to turn servo related functions on and off.
This parameter is not used when machine is equipped with a Haas vector drive. The left and
right cursor arrows are used to select the function being changed. All values are 0 or 1 only.
The function names are:
C LIN SCALE EN Used to enable linear scales for the C axis.
C INVRT LN SCL Used to invert the C-axis linear scale.
C DSBL LS ZTST Used to disable the linear scale Z test.
C ZERO AXIS TC Used to return axis to zero prior to tool change (VR-series).
C 2ND HOME BTN Used to move axis to coordinate specified in Work Offset G129.
C DELAY AXIS 0 Used with an APL to ensure C axis is zeroed before A axis of APL.
Parameter 272 X SCREW COMP T. CONST.
This parameter is the thermal compensation time constant, and is the time constant governing
the rate of cool down of the screw.
Parameter 273 Y SCREW COMP T. CONST.
This parameter is the thermal compensation time constant, and is the time constant governing
the rate of cool down of the screw.
Parameter 274 Z SCREW COMP T. CONST.
This parameter is the thermal compensation time constant, and is the time constant governing
the rate of cool down of the screw.
Parameter 275 A SCREW COMP T. CONST.
This parameter should be set to 0.
Parameter 276 B SCREW COMP T. CONST.
Parameter 276 is used in conjunction with parameter 205 for spindle head thermal
compensation. This parameter should be set to -10,000
Parameter 278 COMMON SWITCH 3
Parameter 278 is a collection of general purpose single bit flags used to turnsome functions on
and off. This bit will cause the machine to use discrete outputs 21 and 26 to command the
shuttle to move in and out. On mills with the Air Driven Shuttle it must be set to 1. On all other
mills it must be set to 0. The left and right cursor arrows are used to select the function being
changed. All values are 0 or 1 only. The function names are:
INVERT G.B. This bit allows an alternate gearbox configuration. It inverts the sense
of the gearbox inputs. Used for 50 taper option.
DPR SERIAL Causes the main serial inputs/outputs to go through the floppy video
board.
CHECK PALLET IN This bit is used on horizontal mills only.
CHECK HIDN VAR This bit is used on horizontal mills only.
