8. interface setup
•
Connect the RS232 serial connectors of your IBM compatible computer and the
NV40/1CLE by using a standard interface line.
•
Switch ON both units.
•
The communication between voltage amplifier and computer can be achieved by
using any terminal program (normally it is part of your operation system, please
refer your OS documentation).
•
RS232 parameters: COMx: 9600,n,8,1
•
You will see an echo on your screen containing the firmware version.
9. how to operate the NV40/1CLE
9.1. common introduction
The voltage amplifier NV40/1CLE was especially developed for one channel positioning
tasks. The primary drive for developing the system was simple service and universal
usage of the unit.
Caution:
The voltage amplifier NV40/1CLE controls piezo elements with integrated measuring
system. In this case, all units, piezo actuator, measuring system and voltage amplifier
must be calibrated on each other. Calibration takes place before the delivery. In open
loop operating mode the output voltage will be displayed, in closed loop operation the
measured motion of the actuator will be displayed.
Please note: If power to the amplifier is lost, the system automatically reverts to the
previously chosen operation mode after power on.
Systems without measuring system:
If you purchased the voltage amplifier without an actuator and/or with an actuator without
measuring system, you can work with it in the non-controlled operation mode. In that
case, we will adjust the display to show the actuator voltage in volts (-10...+150V) instead
of the motion in microns.
In case of a subsequent adaptation of a measuring system, a calibration of the electronics
is necessary. To do so, actuator, electronics and measuring system must be returned to
piezosystem jena
for calibration. There is an additional charge for special calibration.
Please contact your representative to determine if additional calibration is possible.
