Specifications

Operation

On power-on or reboot (with the RBT command), the E-517 copies

information from non-volatile memory to volatile memory. The control mode

is reset to OFFLINE and the servo mode to open-loop operation.

You can define a start-up macro which runs on power-on or reboot, see

"Working with Controller Macros" (p. 37) for more information. To skip the

execution of the start-up macro, press the trackball on the E-517 once

immediately after you have powered on or rebooted the piezo control

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

NOTE

TCP/IP communication: If no DHCP server is available on the network

or if a point-to-point connection between host PC and controller is

being used, after power-on or reboot it might take a period of about 30

seconds before communication is possible.

3.4 How to Command Axis Motion

3.4.1 Applicable Control Sources

The applicable control sources for the axis motion depend on the current

control mode of a piezo channel (OFFLINE or ONLINE mode, see

"Control

Modes"

(p. 23) for details).

In OFFLINE mode, the axis motion is commanded by analog control input

and DC offset applied to the channel. The DC offset plus the analog control

voltage must be in the -2 V to +12 V range. The voltage gain is 10 or 100

(depending on the amplifier type). For detailed information regarding

OFFLINE control see the User Manual of the piezo control electronics

(OFFLINE control may be referred to as "analog operation" there).

In ONLINE mode, the axis motion can be commanded by multiple sources

(see "Control Value Generation" in the E-517 User Manual for details):

■ Move commands (received via interface or from a running macro):

SVA and SVR in open-loop operation; MOV, MVR and GOH in

closed-loop operation; IMP and STE for both servo modes (see

below for examples and

"Servo Modes" (p. 24) for more information)

■ Trackball settings on the CHANNEL SETTING screen (see "Trackball

Functions"

(p. 22) for more information)

■ Wave generator output for periodic motion (see "How to Work with

the Wave Generator

" (p. 36) and “Wave Generator” in the E-517

User Manual for more information and examples)
