Specifications

Operation

■ CHANNEL SETTING, where you can command motion (in ONLINE

mode) or the check current position and voltage (in OFFLINE mode)

for individual channels. See

"Trackball Functions" (p. 22) for details

You can configure the position and voltage display via parameters (e.g.

show / hide channels, set the number of digits). See "Activate/Deactivate

Axes and Channels" in the E-517 User Manual for more information.

3.1.3 Trackball Functions

You can operate the trackball on the E-517 front panel by pressing it or

rolling it left/right or up/down with your fingers. It gives access to the

following functionality:

■ Display screen selection:

You can select the active

display screen (p. 21) by rolling the

trackball to the left or to the right. After power-on or reboot, always

the "main screen" is active (all channels displayed)

■ ONLINE/OFFLINE setting:

When the "main screen" is active, you can switch between ONLINE

and OFFLINE mode for all channels by pressing the trackball (see

"Modes of Operation" (p. 23) for details)

■ Skipping start-up macro:

To skip the execution of the start-up macro, press the trackball once

immediately after you have powered on or rebooted the piezo control

electronics (while "Physik Instrumente" is still shown on the display).

For details about start-up macro definition, see

"Start-Up Macro"

(p.

40)

■ E-517 configuration:

On the DISPLAY SERVICE and COMMUNICATION screens you can

use the trackball to access and modify several settings. See

"Display

Screens"

(p. 21) for details

■ Commanding motion in ONLINE mode:

The CHANNEL SETTING screen gives access to channel-specific

screens. There you can enter target values (position or voltage,

depending on the current servo mode) to move the corresponding

axis. Rolling the trackball left/right selects the digit to be changed,

rolling the trackball up/down selects the value for that digit. You can

switch between the individual channels by pressing the trackball.

While trackball settings and move commands can be used in parallel

to command axis motion, they are not accepted when the wave

generator is running for the axis. See "Control Value Generation" in

the E-517 User Manual for more information.
