Haas Parameters

Haas Parameter 499 C P GAIN Proportional gain in servo loop.

Haas Parameter 500 C D GAIN Derivative gain in servo loop.

Haas Parameter 501 C I GAIN Integral gain in servo loop.

Haas Parameter 480 Tt PHASE OFFSET The motor phase offset for Tt motor. Constant value, the value has no units.

Haas Parameter 481 Tt GRID OFFSET Shifts the effective position of the encoder Z pulse. It can correct for a motor or home switch positioning error.

Haas Parameter 505 C MAX SPEED Maximum speed for this axis in steps per second.

Haas Parameter 529 C LINEAR SCREW OFFS Used on machines with linear scales. This parameter accounts for the unused portion of the ballscrew between zero and the actual motor.

Haas Parameter 506 C MAX ERROR Maximum error allowed in servo loop before alarm is generated. Units are encoder steps. This is the maximum allowable error in Hz between commanded speed…

Haas Parameter 507 C FUSE LEVEL Limits average power to motor. If not set correctly, this parameter can cause an “overload” alarm.

Haas Parameter 510 C BACKLASH Backlash correction in encoder steps.

Haas Parameter 514 C D*D GAIN Second derivative gain in servo loop.

Haas Parameter 516 C PHASE OFFSET The motor phase offset for C motor. Constant value, the value has no units.

Haas Parameter 517 C GRID OFFSET Shifts the effective position of the encoder Z pulse. It can correct for a motor or home switch positioning error.

Haas Parameter 518 C EXACT STOP DIST. This parameter controls how close the axis must be to its end point when exact stop is programmed. They apply in G09 and G64.They…

Haas Parameter 519 C FRICTION COMPENSAT Compensate for friction on the axis. The units are in 0.004V.

Haas Parameter 520 C ACCEL FEED FORWARD Set the feed forward gain for the axis servo. Constant value, it has no units.

Haas Parameter 521 C SCREW COMP. COEF. Coefficient of heating of the ballscrew, and is used to decrease or shorten the screw length.

Haas Parameter 503 C MAX TRAVEL (Steps) Maximum negative direction of travel from machine zero in encoder steps. Does not apply to A-axis. A 20-inch travel, 8192 line encoder and 6…

Haas Parameter 522 C AIR BRAKE DELAY Delay provided for air to release from the brake prior to moving. Units are milliseconds.

Haas Parameter 504 C ACCELERATION Maximum acceleration of axis in steps per second per second.

Haas Parameter 528 C SCALE GAIN MULT Used on machines with linear scales. Linear scales are used to continuously correct any errors in encoder position. The parameter determines the gain of…

Haas Parameter 537 Ss I GAIN Integral gain in servo loop.

Haas Parameter 549 Ss MAX CURRENT Sets maximum current allowed from the vector drive to the spindle motor: 4095 = max.

Haas Parameter 572 C AXIS ENG TIMEOUT – Haas Lathe Specifies the C-axis timeout value for seeing the engaged switch on engagement or the disengaged switch on disengage. The units are…

Haas Parameter 550 Ss MAG CURRENT Magnetization component of the current in the motor, also called the flux or field current.

Haas Parameter 551 Ss SPIN ORIENT MARGIN When a spindle orientation is done, if the actual position of the spindle is within this value (plus or minus), the spindle will be…

Haas Parameter 552 Ss SPINDLE STOP FREQ Spindle considered stopped (discrete input SP ST*=0) when speed drops below this value. Units are encoder steps/millisecond.

Haas Parameter 553 Ss START/STOP DELAY This delay is used at the start of motion to magnetize the rotor before acceleration starts. When the motor comes to a stop it remains…

Haas Parameter 538 Ss SLIP GAIN Calculated slip rate depends on two other variables: speed and current. Slip rate = slip gain x (speed/max speed) x (current/max current). The slip gain…

Haas Parameter 555 Ss SWITCH FREQUENCY Frequency at which the spindle motor windings are switched. Note that there is a hysteresis band around this point, defined by Parameter 198.

Haas Parameter 539 Ss MIN SLIP Minimum value allowed from the slip rate. From the equation: Slip rate = slip gain x (speed/max speed) x (current/max current). It can be…
