Cal to LS Velocity Parameters

The Cal to LS Velocity parameters set the feed rate for each axis as it is moving towards the calibration limit switch during a machine calibration cycle. Only the axes that are present on the machine need to be set. The units are indicated in parentheses and can be MMPM (millimeters per minute), IPM (inches per minute), or DPM (degrees per minute).

  • The default setting for Calibrate to Limit Switch Velocity is 1270 MMPM (50 IPM) for the X, Y, and Z axes. The range for Cal to LS Velocity values for the X, Y, and Z axes is 100 MMPM to 2540 MMPM.

  • The default setting for Calibrate to LS Velocity is 0 DPM for the A, B, and C axes. The range for Cal to LS Velocity values for the A, B, and C axes is 100 DPM to 2540 DPM.

  • The default setting for Calibrate to Limit Switch Velocity is 1270 mmpm (50 IPM) for X, Y, and Z axes.

  • The default setting for Calibrate to Limit Switch Velocity is 1000 mmpm (39.37 IPM) for A axis on a VTXU machine.

  • The default setting for Calibrate to Limit Switch Velocity is 2000 (78.74 IPM) mmpm for B axis on an HMX machine.

  • The default setting for Calibrate to Limit Switch Velocity is 1000 mmpm (50 IPM) for C axis on a VTXU machine.

Warm Up Parameters

These parameters allow the operator to configure the machine’s daily warm-up cycle.

  • Warm-up Cycle Time Per Pass

  • Warm-up Starting Speed

  • Warm-up Speed Steps

  • Warm-up Max Spindle Speed

  • Warm-up Axis Feed Rate

When the warm-up cycle is initiated:

  • Spindle speeds up to the Warm-up Starting Speed RPM for the time indicated in the Warm-up Cycle Time per Pass field.

  • X and Y axes move diagonally from corner to corner at the Warm-up Axis Feed Rate.

  • The machine then steps through the warm-up cycle until the Warm-up Max Spindle Speed is reached. The length of each step is defined by the Warm-Up Cycle Time per Pass. During each step of the cycle, the spindle speed will increase to the Warm-up Speed Steps RPM and the axes will run at the Warm-up Axis Feed Rate.

Altering the default daily warm-up parameters may lead to inadequate machine warm up that can negatively impact spindle operations and may void the Hurco warranty.

Refer to your machine’s Maintenance and Safety manual for more information about warm-up cycles.

Spindle Lube/Warm-Up Max Speed

Use this parameter to set the maximum speed (RPM) for the spindle during the pre-lube and warm-up cycle.
