Haas Parameter 495 Tt SCALES PER REV Used on machines equipped with linear scales.

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 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 541 Ss MAX FREQ See Parameter 8 for description. Frequency at which the motor will be run when maximum spindle rpm is commanded. Units: 0.01 Hz (two implied decimal…

Haas Parameter 542 Ss MAX ERROR Maximum allowable error (in Hz) between commanded spindle speed and actual speed. If set to zero, it will default to 1/4 of Parameter 183.

Haas Parameter 543 Ss FUSE LEVEL See Parameter 10 for description.

Haas Parameter 544 Ss DECELERATION See Parameter 10 for description. Maximum deceleration of axis in encoder steps per second per second.

Haas Parameter 546 Ss ORIENT GAIN Proportional gain used in the position control loop when performing a spindle orientation.

Haas Parameter 547 Ss BASE FREQ Rated frequency of the motor.

Haas Parameter 548 Ss HI SP CURR LIM At speeds higher than the base frequency, the maximum current that is applied to the motor must be reduced. This is done linearly…

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…
