6. PARAMETERS
Parameters are seldom-modified values that change the operation of the machine. These include servo motor
types, gear ratios, speeds, stored stroke limits, ball screw compensations, motor control delays and macro
call selections. These are all rarely changed by the user and should be protected from being changed by the
parameter lock setting. If you need to change parameters, contact HAAS or your dealer . Parameters are
protected from being changed by Setting 7.
The Settings page lists some parameters that the user may need to change during normal operation and these
are simply called "Settings". Under normal conditions, the parameter displays should not be modified. A
complete list of the parameters is provided here.
The PAGE UP, P AGE DOWN, up and down cursor keys , and the jog handle can be used to scroll through the
parameter display screens in the control. The left and right cursor keys are used to scroll through the bits in a
single parameter .
PARAMETER L IST
1 X SWITCHES
Parameter 1 is a collection of single-bit flags used to turn servo related functions on and off.
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:
0 REV ENCODER Used to reverse the direction of encoder data.
1 REV POWER Used to reverse direction of power to motor.
2 REV PHASING Used to reverse motor phasing.
3 DISABLED Used to disable the X-axis.
4 Z CH ONLY With A only, indicates that no home switch.
5 AIR BRAKE With A only, indicates that air brake is used.
6 DISABLE Z T Disables encoder Z test (for testing only).
7 SERVO HIST Graph of servo error (for diagnostics only).
8 INV HOME SW Inverted home switch (N.C. switch).
9 INV Z CH Inverted Z channel (normally high).
10 CIRC. WRAP . With A only, causes 360 wrap to return to 0. Note for parameter 498 bit 10:
When the bit is set to 1, the lathe will automatically unwind the C-axis no
more than half a rotation. When the bit is set to zero, it behaves as if the C
axis had been rotated many times then disengaged, when it is engaged
again, the control will zero it by unwinding as many times as it had been
wound.
11 NO I IN BRAK With A only, removes I feedback when brake is active.
12 LOW PASS +1X Adds 1 term to low pass filter.
13 LOW PASS +2X Adds two terms to low pass filter.
14 OVER TEMP NC Selects a normally closed overheat sensor in motor.
15 CABLE TEST Enables test of encoder signals and cabling.
16 Z TEST HIST History plot of Z channel test data.
17 SCALE FACT/X If set to 1, the scale ratio is interpreted as divided by X; where X depends
on bits SCALE/X LO and SCALE/X HI.

to 1, the CNC will access it at power-on time and display the message
“LOADING” on the Zip/Enet settings page just below setting 139. After
some time (2 minutes maximum,) the control will instead display the
message “DISK DONE” indicating that communications have been
established with the internal PC104 board and the user can now use the
control.

enabled with an unlock code. The unlock code will be printed on the
parameter listing of all new machines. If this bit is set to 0, an M19 will
orient the spindle to 0 degrees regardless of the value of any P or R code
in the same block. If this is set to 1, a P code in the block will cause the
spindle to be oriented to the specified angle such as P180. Alternately, a
decimal R code can be used, such as R180.53. Note that the P and R

29 NC OVER VOLT Inverts sense of over voltage signal.
30 SP MOTOR ENC This parameter bit enables a second encoder that is mounted on the
spindle motor and wired into the “C” axis input of the Mocon. It is required
to control the vector algorithm on a belted machine when the belts slip at
high load.
When two encoders are present, the first is mounted on the spindle or
output of the transmission, and is wired to the “spindle” input on the
MOCON.
Most mills use a single encoder that is mounted on either the spindle
(transmission output) or spindle motor but always connected to the
spindle input on the Mocon.

187 C sp MOT HI GEAR ST/REV
This name is used when a Vector Drive is inst alled. This function takes on two meanings
depending on how many spindle encoders are used on the machine. If only one encoder is
present, it is the number of encoder steps per mechanical revolution of the spindle motor when
the transmission is in high gear. (On direct drive machines, the encoder is mounted on the
motor, while on others, it is on the spindle or transmission output.) N = (Encoder step s/enc
rev)/(Enc pulley ratio X High Gear Ratio) For machines with a spindle and spindle motor
encoder, it is the number of spindle motor encoder steps per mechanical revolution of the
encoder. It s purpose is to specify the resolution of the spindle motor encoder. This parameter
is used in conjunction with parameter 176 bits 25 and 26, which control the ratio between the
electrical revolution of the motor to the mechanical revolution of the encoder.
If a vector drive is not installed, this parameter is called: STEPS/REVOLUTION and is not
used.
188 C ORIENT GAIN

to help prevent collisions between tools mounted on the outside of the
turret and a sub-spindle mounted on the tailstock. It is important to note
that a single axis HOME G28 (e.g., press Z then HOME G28) and any G28
specified in a program will still cause the axis to move regardless of the

291 HYDRAULIC T AIL STK NO MOTION DETEC TIME
The number in milliseconds that must pass with no B-axis encoder change before the control
decides that the tailstock has stopped. The parameter affects homing and alarm situations on
the tailstock. If the tailstock pressure is set low and the tailstock does not home properly then
increase this parameter .
292 HYD TS RTRACT MARGN (Hydraulic Tailstock Retract Margin)
This parameter sets the acceptable range, in encoder steps, for the retract point. When the
tailstock stops anywhere within this range, the control assumes it is at the retract point. The
default is 5 encoder steps. This means that a 10 encoder step range is set around the retract
point.
293 HYD TS SLOW DISTNCE (Hydraulic Tailstock Slow Distance)
This parameter sets the distance, prior to a target point, where the tailstock will transition from
a rapid movement to a feed. For example, if this parameter is set to 30 (the default), this
means the tailstock will slow to a feed 30 encoder steps before reaching the target point. Units
are in encoder steps.
294 MIN BUSS VOL T AGE
This parameter specifies the minimum Haas Vector Drive buss volt age. If the machine has a
Haas Vector Drive, the p arameter should be set to 270 (volts). Machines without a V ector Drive
should be set to 0. Alarm 160 LOW VOLTAGE will be generated if the voltage falls below the
minimum specified.

NOTE: The operator may use the feed rate override buttons while the AUTOFEED feature is active.
As long as tool load limit is not exceeded, these buttons will have the expected effect
and the overridden feed rate will be recognized as the new commanded feed rate by
the AUTOFEED feature. However, if the tool load limit has already been exceeded, the
control will ignore the feed rate override buttons and the commanded feed rate will
remain unchanged.

ELECTRONIC T HERMAL C OMPENSATION
When ballscrews rotate they generate heat. Heat causes the ballscrews to expand. In constant duty cycles,
the resultant ball screw growth can lead to cutting errors on the next morning start up. Haas' ETC algorithm
can accurately model this heating and cooling effect and electronically expand and contract the screw to give
near glass scale accuracy and consistency .
This compensation is based on a model of the ball screw which calculates heating based on the distance
traveled and the torque applied to the motor. This compensation does not correct for thermal growth due to
changes in ambient temperature or due to part expansion.
Electronic thermal compensation works by estimating the heating of the screw based on the total amount of
travel over its length and including the amount of torque applied to the screw. This heat is then turned into a
thermal coefficient of expansion and the position of the axis is multiplied by the coefficient to get a correction
amount.
If the machine is turned off when there is some compensation applied (due to motion and heating of screw),
when the machine is turned back on, the compensation will be adjusted by the clock indicated elapsed time.
SPINDLE H EAD T HERMAL C OMPENSATION
This feature integrates spindle speed over time and builds a model of thermal growth. As the model shows the
spindle head warming up, the control adjusts the axes to compensate for thermal growth.
X-AXIS T HERMAL C OMPENSATION
During machining, the heating of the ballscrews transfers heat by conduction to the thermal sensor body. This
causes the resistance of the sensor to vary according to the temperature. The resistance value is read by the
software which compensates for the change in temperature by adjusting the accuracy of the program accordingly .
The thermal sensor is connected to the ballscrew and compensates program accuracy for changes in
ballscrew temperature.
