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)
PC INTERFACE
serial RS232 interface or USB1.1 (see 8.3)
REMOTE CONTROL
The remote control switches all manual controls (ENCODER KNOB and MODULATION) off
or on. Please pay attention only if the remote control is switched on (1) it will be possible to
use the „set" command.
HYPER TERMINAL PROGRAM
This software enables to control the piezo actuating system by using the RS232 interface.
The available commands are described in chapter 8.3.2.
ASI function (Automatical Sensor Identification)
NV40/3CLE, NV120/1CLE amplifiers can be used with strain gauge feed back sensors as
well as with capacitive feed back sensors. The ASI function makes it possible to show the
name of the actuator and the measurement system.
Soft Start
Initialization after turning-on procedure. During initialization sequence the piezo electrical
actuator is controlled for approximately 10 seconds with a voltage signal from -20V up to
130V. Please note: the actuating system is moving!
