7 NV40/3, NV40/3CLE, NV120/1 and NV120/1CLE
These voltage amplifiers are very similar. In case of information which do refer to the
NV40/3CLE or NV12
0/1CLE the symbol “
→ not available in NV40/3, NV120/1” will point it.
NV40/3
piezo amplifier for up to 3 PZT actuators; RS232/USB interface; for piezo actuating systems
without feed back sensor inside
NV40/3CLE
piezo amplifier for up to 3 PZT actuators; RS232/USB interface; for piezo actuating systems
with feed back sensors inside (strain gauge or capacitive)
NV120/1
piezo amplifier for one PZT actuator; RS232/USB interface; for piezo actuating system
without feed back sensor inside
NV120/1CLE
piezo amplifier for one PZT actuator; RS232/USB interface; for piezo actuating system with
feed back sensor inside (strain gauge or capacitive)
7.1 key words
GRAPHIC DISPLAY
dimmable
3.5“ TFT full colour graphic, 320x240 Pixel; constantly shows all values and status
information
ENCODER KNOB
for manually voltage or position adjustment and for switching on/off the CLOSED LOOP
mode (NV40/3CLE only)
CLOSED LOOP
operating mode for piezo actuating systems with integrated feed back sensor system,
position accuracy is constantly controlled
OPEN LOOP
operating mode for actuating systems without feedback sensor inside; no position
information available
MODULATION INPUT
the amplifier can be controlled by an applied
analogue voltage signal from 0V…+10V
(see 8.2.1)
MONITOR OUTPUT
output voltage signal which corresponds with the position of the piezo actuating system
(CLOSED LOOP mode) or with the applied voltage signal (OPEN LOOP mode), (see 8.2.2)
