Specifications

Operation
Hardware: A piezo stage and an E-500 chassis with one E-505 amplifier
module and E-517 (single-channel system).
Command
String to Send
Response Action Performed
ONL 1 1
Switch piezo channel 1 (identifiers 1) to
ONLINE mode so that axis motion can be
caused by move commands (received via
interface or from a running macro), wave
generator output and trackball settings
SVO? A A=0
Check current servo mode for axis A. The axis
is in open-loop operation (response = 0), i.e.
there is no correction of drift or other effects.
SVA A 80
Move axis A by setting the corresponding
output voltage to 80 volts.
VOL? 1 1=+0079.9742
Query the current output voltage of piezo
channel 1 which drives axis A.
SVA A 150
Attempt to set the output voltage for axis A to
150 volts.
VOL? 1 1=+0079.9725
The last commanded voltage value lay beyond
the allowed range and the SVA command
therefore was ignored.
SVA? A A=+0080.0000
Query the commanded output voltage. It
resulted from the last valid SVA command.
VMA? A A=+0120.0000
Get voltage output high limit for the axis.
VMA A 90
Set voltage output high limit for the axis to 90
volts.
VMI A 10
Set voltage output low limit for the axis to 10
volts.
SVA A 85
Set the output voltage for axis A to 85 volts.
VOL? 1 1=+0085.4611
Query the current output voltage of piezo
channel 1.
SVA A 100
Set the output voltage for axis A to 100 volts.
VOL? 1 1=+0085.4606
Query the current output voltage of piezo
channel 1.
