Haas Parameter 390 V SWITCH A


Haas Parameter 390 V SWITCH A

Parameter 390 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 – Reverses the direction of encoder data.
  • 1 REV POWER – Reverses the direction of power to motor.
  • 2 REV PHASING – Reverses motor phasing.
  • 3 DISABLED – Disables the X-axis.
  • 4 Z CH ONLY – With A only, indicates no home switch.
  • 5 AIR BRAKE – With A only, indicates 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 (NC switch).
  • 9 INV Z CH – Inverted Z channel (normally high).
  • 10 CIRC. WRAP. (L) – When Parameter 498 bit 10, is set to 1, the lathe automatically unwinds 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 and disengaged. When it is engaged again, the control zeroes it by unwinding as many times as it was wound.
  • 10 CIRC. WRAP. (M) – With A only, causes 360 wrap to return to 0.
  • 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.
  • 18 INVIS AXIS – Creates an invisible axis.
  • 19 (L) DIAMETER PRG – Sets diameter programming. When set to 1, it interprets inputs as diameter instead of radii.
  • 19 (M) ALM ON LM SW – Rotary alarms at the limit switch.
  • 20 (L) TRAVL LIMITS – Travel limits are used.
  • 20 (M) CK TRAVL LIM A – Rotary travel limits are used. On mills with the Gimbaled Spindle (used on the VR series mills), A and B axes CK TRAVL LIM must be set to 1.
  • 21 (L) NO LIMSW ALM – Alarms are not generated at the limit switches.
  • 21 (M) ROT TRVL LIM – Rotary travel limits are used.
  • 22 D FILTER X8 – Enables 8 tap FIR filter on the derivative component of the servo loop. Used to eliminate high frequency vibrations (depending on axis motor).
  • 23 D FILTER X4 – Enables 4-tap FIR filter on the derivative component of the servo loop. Used to eliminate high frequency vibrations (depending on axis motor).
  • 24 TORQUE ONLY – For Haas diagnostic use only.
  • 25 3 EREV/MREV – The 2 EREV/MREV and 3 EREV/MREV bits have two definitions, depending on whether one or two encoders are present. For single encoder systems, the bits are used to define the ratio between the electrical rotation of the spindle motor and the mechanical rotation of the motor. For two encoder systems, the definition is the electrical rotation of the motor to the mechanical rotation of the spindle motor encoder, which includes any pulley ratio between the motor and the motor encoder.
  • 26 2 EREV/MREV – The 2 EREV/MREV and 3 EREV/MREV bits have two definitions, depending on whether one or two encoders are present. For single encoder systems, the bits are used to define the ratio between the electrical rotation of the spindle motor and the mechanical rotation of the motor. For two encoder systems, the definition is the electrical rotation of the motor to the mechanical rotation of the spindle motor encoder, which includes any pulley ratio between the motor and the motor encoder.
  • 27 NON MUX PHAS – For Haas diagnostic use only.
  • 28 BRUSH MOTOR – Enables the brushless motor option.
  • 29 (L) ROTARY AXIS – When set to 1, the axis is treated as a rotary axis. Position will be displayed in degrees, and inputs will be interpreted as angles.
  • 29 (M) LINEAR DISPL – Changes the display from degrees to inches (or millimeters) on the A and B axes.
  • 30 SCALE/X LO – With SCALE/X HI bit, determines the scale factor used in bit SCALE FACT/X.
  • 31 SCALE/X HI – With SCALE/X LO bit, determines the scale factor used in bit SCALE FACT/X. See below:
