Moving the machine axes

Application

Description of function

The control offers the following methods for moving axes manually:

  • Axis-direction keys
  • Incremental jog positioning with the Jog increment button
  • Traversing with electronic handwheels
  • Electronic handwheel

The control displays the current contouring feed rate in the status display while the machine axes are in motion.

Status displays

You can change the contouring feed rate with the F button in the Manual operation application and with the feed-rate potentiometer.

A traverse job is active on the control as soon as an axis moves. The control shows the status of the traverse job with the Control-in-operation icon in the status overview.

Using axis keys to move the axes

To move an axis manually with the axis keys:

    1. Select an operating mode (e.g., Manual)

    1. Select an application (e.g., Manual operation)

    1. Press the axis key of the desired axis
    2. The control moves the axis as long as you press the key.
     
    Tip

    If you hold the axis key pressed down and simultaneously press the NC start key, the control moves the axis at a continuous feed rate. You have to end traverse movement with the NC stop key.

    You can move more than one axis at a time.

    Incremental jog positioning of axes

    Incremental jog positioning allows you to move a machine axis by a preset distance. The input range for the infeed is from 0.001 mm to 10 mm.

    To position an axis incrementally:

      1. Select the Manual operating mode

      1. Select the Manual operation application

      1. Select Jog increment
      2. The control opens the Positions workspace, if necessary, and shows the Jog increment area.

      1. Enter the jog increment for linear axes and rotary axes

      1. Press the axis key of the desired axis
      2. The control positions the axis in the selected direction by the defined jog increment.

      1. Select Off
      2. The control ends incremental jog positioning and closes the Jog increment area in the Positions workspace.
       
      Tip

      You can also end incremental positioning with the Jog inc. on button.

      Note

      When positioning an axis, the control checks whether the defined speed has been reached. The control does not check the speed in positioning blocks where FMAX is the feed rate.
