Specifications

Operation

While move commands and trackball settings can be used in parallel to

command axis motion, they are not accepted when the wave generator is

running for the axis.

The macro feature allows defining command sequences and storing them

permanently in non-volatile memory in the controller. Macros can run in

OFFLINE and ONLINE mode, but move commands from macros are only

accepted in ONLINE mode and only when the wave generator is not

running. See

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

The E-517 has a real-time data recorder. It is able to record several input

and output signals from different data sources during the axis motion. Data

recording is triggered automatically with four commands:

■ STE (step response measurement),

■ IMP (impulse response measurement),

■ WGO (wave generator start) and

■ WGR (restarts recording when the wave generator is running).

Recording always takes place for all data recorder tables and ends when

the data recorder tables are completely filled. See

"Data Recording" (p. 31)

for more information.

It is possible to trigger external devices during the axis motion and to send

start/stop signals to the wave generators with the digital I/O lines of the

E-517. See "External Triggering / Signaling" in the E-517 User Manual for

more information and examples and

"Digital In/Out Socket" (p. 71) for the

lines and pinout.

3.4.2 Command Examples for ONLINE Mode

The following examples can be used in a terminal, e.g. in the Command

Entry

window of PIMikroMove™ or in the PI Terminal.

Example 1:

This example moves axis A of the mechanics in open-loop operation. The

output voltage is varied to see the influence of the voltage limits for the

corresponding piezo channel: hardware limits are given by parameters

0x0B000007 and 0x0B000008 and can not be changed, "soft limits" can be

set with VMA and VMI. In this example, the output voltage will be limited to

the range of +10 to +90 volts.
