Tip

On handwheels with display the speed level defines only the distance per detent stop; it does not define the feed rate for traverse movements with axis-direction keys.

You use the MSF soft key to define the feed rate.

Defining the handwheel feed rate F

Special features of the HR 550 FS wireless handwheel

With the HR 550 FS wireless handwheel you can move farther away from the machine operating panel than with cable-connected handwheels. The HR 550 FS wireless handwheel thus provides an important benefit, in particular for large machines.

The HRA 551 FS handwheel holder and the HR 550 FS handwheel together form one functional unit.

HR 550 FS handwheel

HRA 551 FS handwheel holder

The HR 550 FS wireless handwheel features a rechargeable battery. The battery starts charging when you place the handwheel into the holder.

The HR 550 FS can be operated by battery for up to eight hours before it needs recharging. A completely discharged handwheel takes approx. three hours for a full charge. When you aren't using the HR 550 FS, always place it in the handwheel holder. This charges the handwheel battery constantly and a direct connection with the emergency-stop circuit is provided.

When the handwheel is in its holder, it provides the same functionality as during radio mode. This allows you to use a completely discharged handwheel.

 
Tip

Clean the contacts of the handwheel holder and handwheel regularly to ensure their proper functioning.

You can configure wireless handwheels in the TNCdiag application.

Setting up a wireless handwheel

If the control has triggered an emergency stop, you must reactivate the handwheel.

If you happen to get close to the limit of the transmission range, the HR 550 FS will set off a vibrating alarm. If this occurs, you must reduce the distance to the handwheel holder.

Activating and deactivating a handwheel with display

 
Notice
Caution: Possible damage to the workpiece!
When toggling between the machine operating panel and the handwheel, the feed rate may be reduced. This can cause visible marks on the workpiece.
  1. Retract the tool before switching
  2. Before switching, check whether the settings of the feed-rate potentiometers match

To activate a handwheel with display:

    1. Press the Handwheel key on the handwheel
    2. The NC control activates the handwheel and changes the symbol in the Manual operating mode.
    3. The control displays a handwheel symbol next to the currently selected axis in the Position workspace.

    1. If necessary, adjust the setting of the feed-rate potentiometer

    To deactivate a handwheel with display:

      1. Press the Handwheel key on the handwheel
       
      Tip

      The control also activates or deactivates the feed-rate potentiometer.

      If the feed rate before switching is higher than the feed rate after switching, the control automatically reduces the feed rate to the smaller value.

      If the feed rate before switching is less than the feed rate after switching, the control automatically freezes the feed rate. In this case, you must turn the feed-rate potentiometer back to the previous value because only then will the activated feed-rate potentiometer take effect.

      Creating an NC block with the current position

       
      Machine

      Refer to your machine manual.

      The machine manufacturer can assign any keys on the handwheel. Your handwheel therefore might not have an actual position capture key.

      To create an NC block using the handwheel:

        1. Select the Manual operating mode

        1. Select the MDI application
        2. If necessary, select the NC block after which you want to insert the NC block
        3. Activate the handwheel

        1. Press the actual position capture key
        2. The control inserts a straight line L with the actual positions of all defined axes.
         
        Tip

        You use the actPosAxes machine parameter (no. 105415) to define the axes used by the actual position capture key to create a straight line L.

        Defining the spindle speed S

        To define the spindle speed S of the active spindle when using a handwheel with display:

        1. Press the MSF soft key on the handwheel
        2. Press the S soft key on the handwheel
        3. Select the desired spindle speed by pressing the F1 or F2 keys
        4. The handwheel shows the defined spindle speed in the display after S.
        5. Press the NC Start key
        6. The control activates the defined spindle speed.
         
        Tip

        If you press and hold the F1 or F2 key, the handwheel counts the value up or down. The longer you press the key, the greater the counting step.

        If you additionally press the CTRL key, the handwheel starts with a larger counting step.

        Defining the handwheel feed rate F

        To define the feed rate F when using a handwheel with display:

        1. Press the MSF soft key on the handwheel
        2. Press the F soft key on the handwheel
        3. Select the desired feed rate by pressing the F1 or F2 keys
        4. Press OK
        5. Confirm the new feed rate by pressing the OK soft key on the handwheel

        1. Press an axis key

        1. Press a traverse direction key
        2. The control moves the axis at the defined feed rate.
         
        Tip

        If you press and hold the F1 or F2 key, the control will increase the counting increment by a factor of 10 each time it reaches a value divisible by 10.

        By additionally pressing the CTRL key, you can increase the counting increment by a factor of 100 when pressing F1 or F2.

        Incremental jog positioning

        Incremental jog positioning allows you to move the selected axis by a defined value each time you press a key.

         
        Tip
        • Incremental jog positioning works only for traverse movements using the axis-direction keys.
        • The control compares the settings for incremental jog positioning defined for the handwheel and the control.

        To perform incremental jog positioning using a handwheel with display:

        1. Press the STEP soft key on the handwheel
        2. Press the ON soft key on the handwheel
        3. The control activates incremental jog positioning.
        4. Select the desired jog increment by pressing the F1 or F2 keys
        5. The handwheel shows the defined jog increment in the display after STEP.
        6.  
          Tip

          The smallest possible increment is 0.0001 mm (0.00001 inches). The largest possible increment is 10 mm (0.3937 inches).

        7. Confirm the jog increment by pressing the OK soft key on the handwheel

        1. Press an axis key

        1. Press a traverse direction key
        2. The control moves the axis by the defined jog increment.
         
        Tip

        If you press and hold the F1 or F2 key, the control will increase the counting increment by a factor of 10 each time it reaches a value divisible by 10.

        By additionally pressing the CTRL key, you can increase the counting increment by a factor of 100 when pressing F1 or F2.

        Notes on wireless handwheels

         
        Danger
        Caution: hazard to the user!
        Wireless handwheels, due to their rechargeable batteries and the influence of other wireless devices, are more susceptible to interference than cable-bound connections are. Ignoring the requirements for and information about safe operation leads to endangerment of the user, for example during installation or maintenance work.
        1. Check the radio connection of the handwheel for possible overlapping with other wireless devices
        2. Switch off the handwheel and the handwheel holder after an operating time of 120 hours at the latest so that the control can run a functional test the next time it is restarted (only for handwheels 598515-03, 606622-03 and holder 731928-02)
        3. If more than one wireless handwheel is being used in a workshop, then ensure an unambiguous assignment between the handwheels and the handwheel holders (such as with color-coded stickers)
        4. If more than one wireless handwheel is being used in a workshop, then ensure an unambiguous assignment between the handwheels and the respective machine (such as with a functional test)
         
        Notice
        Caution: Danger to the tool and workpiece!
        The wireless handwheel triggers an emergency stop reaction if the radio transmission is interrupted, the battery is fully empty, or if there is a defect. Emergency stop reactions during machining can cause damage to the tool or workpiece.
        1. Place the handwheel in the handwheel holder when it is not in use
        2. Keep the distance between the handwheel and the handwheel holder small (pay attention to the vibration alarm)
        3. Test the handwheel before machining
        • The control displays a warning if you connect a wireless handwheel with an already selected radio channel.
