Handwheel soft keys
You can use the handwheel soft keys to select the following functions:
Soft key | Key | Meaning |
---|---|---|
AX | F1 | Select machine axis |
STEP | F2 | Active or deactivate incremental jog positioning, and select the jog increment |
MSF | F3 | Define cutting data, miscellaneous functions, and presets |
OPM | F4 | Select operating mode |
MA | F5 | Execute machine-specific functions (such as switching magazine pockets) |
MOP | F3 | Select manual options Only if program run was interrupted by an NC stop |
Operating modes
Press OPM to choose between the following operating modes:
Soft key | Key | Meaning |
---|---|---|
MAN | F1 | Manual operating mode |
MDI | F2 | MDI application in the Manual operating mode |
RUN | F3 | Program Run operating mode |
SGL | F4 | Single Block mode in the Program Run operating mode |
Functions during program run
Press MOP to choose between the following functions:
Soft key | Key | Meaning |
---|---|---|
MAN | F1 | Manual traverse |
STOP | F4 | Internal stop |
Press MAN at this level to choose between the following functions:
Soft key | Key | Meaning |
---|---|---|
REPO | F1 | Return to the contour |
3D | F2 | Settings of the Tilt working plane function |
Speed levels
You use the up and down arrow keys to choose the speed level.
The handwheel shows the value of the selected level in the display after RES. If you rotate the wheel by one detent stop, the control moves the axis by the value in the unit of measure for that axis.
Key | Meaning |
---|---|
Increase speed level | |
Decrease speed level |
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.
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.
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
- Retract the tool before switching
- Before switching, check whether the settings of the feed-rate potentiometers match
To activate a handwheel with display: | ||

|
To deactivate a handwheel with display: | ||

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
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: | ||
| ||
| ||
|
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:
- Press the MSF soft key on the handwheel
- Press the S soft key on the handwheel
- Select the desired spindle speed by pressing the F1 or F2 keys
- The handwheel shows the defined spindle speed in the display after S.
- Press the NC Start key
- The control activates the defined spindle speed.
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:
| ||
| ||
|
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.
- 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:
| ||
| ||
|
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
- Check the radio connection of the handwheel for possible overlapping with other wireless devices
- 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)
- 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)
- 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)
- Place the handwheel in the handwheel holder when it is not in use
- Keep the distance between the handwheel and the handwheel holder small (pay attention to the vibration alarm)
- Test the handwheel before machining
- The control displays a warning if you connect a wireless handwheel with an already selected radio channel.
