6.2 Installation & power supply RISK OF ELECTRIC SHOCK! • Do not insert or unplug the power plug with wet hands, as this may result in electrical shock. • Do not install in rooms where inflammable substances are stored. If flammable substances come into contact with electrical parts inside, it could result in fire or electrical shock. -
Page 8: Maintenance And Inspection
Maintenance and inspection CAUTION! • Before cleaning the exterior box of the voltage amplifier, turn off the power switch and unplug the power plug. Failure to do so may result in a fire or electrical shock. • Clean the exterior box using a damp cloth that has been firmly wrung-out. Do not use alcohols, benzene, paint thinner or other inflammable substances. -
Page 9: How To Operate The Digital Amplifier Nv200/D Net
The actuator is connected to the NV200/D NET using the “PIEZO” plug. After switch on, the device runs a self-test procedure, while the indicator LED is lightning red. This takes about 3 s. During this step the controller reads the system specific parameters from the actuators ID-chip and sets up the controller. -

Page 14: Establishing Communication
8.4 Establishing communication 8.4.1 Serial communication via USB The NV200/D NET can easily communicate with your PC with the use of a terminal program such as HTerm. A USB connection cable (included) is required to connect to your computer. The properties of the COM port are: 115200 baud, 8 bit, no parity, 1 stop bit, software handshake (XON / XOFF). - Page 15 Alternatively, you can use other programs like Putty. After successful connection the full command set is available. The Telnet connection can be established via the IP address of the controller and the correct port number. The default port number is 23. By default, the IP address is set dynamically over DHCP.
- Page 16 8.4.3 Ethernet configuration The network settings can be changed via Telnet connection (port: 9999) or via a web browser. It is possible to change the IP address and the default port (23) for Telnet communication with the device. Under the item “Server” the IP address can be set to a static one or to DHCP. Under item “Channel 1”...
- Page 17 8.4.4 SPI communication Real-time communication can take place via the SPI interface. The device works as an SPI slave, i.e. the device receives setpoints from an external SPI master. The return value retrieved over the MISO channel can be set to different quantities (e.g. position values) via the USB or Ethernet interfaces. The SPI connection is exclusively to send setpoints to the device.

Page 18: Command List
To synchronize the NV200/D NET PID controller loop execution to the SPI master the spitrg option can be used. In mode spitrg,0 the internal 20 kHz clock is used to trigger the digital control loop interrupt. In mode spitrg,1 the digital control loop interrupt is executed only when a new SPI setpoint is received. - Page 19 0 = set-Command via USB or Ethernet modsrc Signal source for setpoint 1 = Analog In 2 = SPI 3 = Arbitrary waveform generator monsrc Source of data for analog output 0 = position (closed loop) 1 = setpoint 2 = piezo voltage (controller output) 3 = position error 4 = abs(position error) 5 = position (open loop)

Page 23: Status Register
8.7 Status register The status register is a 16bit register, in which each bit describes a certain setting of the amplifier or actuator. The decimal sum of all bits is the value of the status register. It can be requested by the stat command. -

Page 28: Data Recorder
Various controller functions can be carried out with the trigger input. This can be used to synchronize the controller with several other NV200/D NET controllers or any other external device. The trigger input uses a 5V logic and is activated by rising edges. -
Page 29: Temperature Measurement
8.11.2 Trigger Out In order to control external devices, the measured or desired (setpoint) position can be reported back via the trigger output. The input signal for the trigger can be chosen via trgsrc command. The trigger signal is low-active, i.e. an H / L edge shows that a trigger point has been reached. The signal range in which trigger events are generated is determined with trgss (lower limit) and trgse (upper limit). -
