Warnings, Cautions, and Notes throughout this user manual and, where visible, on the ANC300 itself. I.2.a. Safety Symbols on the Equipment WARNING. Risk of electric shock. High voltages present.
WARNING. Risk of electric shock. If covers are opened, there is a risk to touch hazardous voltages. If malfunction is suspected, immediately con- tact attocube systems for repair or replacement. Modified or opened elec- tronics cannot be covered by the attocube warranty anymore. Only per- sonnel trained in the servicing and maintenance of this equipment should remove its covers or attempt any repairs or adjustments.
Waste treatment on your own responsibility If you do not return an "end of life" product to attocube systems, you must hand it to a company specialized in waste recovery. Do not dispose of the unit in a litter bin or at a public waste disposal site.
2) After switching off, always wait 2 minutes before opening the ANC300, and before removing or inserting any module or card. 3) Always replace broken fuses with fuses of the same type and rating. Two main fuses are located on the back panel for the mains voltage.
II.3. Front Panel Controls and Indicators Figure 1: Front panel of the ANC300 with seven ANM modules in place. The front panel is arranged as follows: 1) Main display with touch screen functionality (CPU behind it), 2) View knob to move the focus in the main screen, 3) Edit knob to change values and activate options, 4) Power supply.
II.4. Back Panel Connections Figure 3: Back panel of the ANC 300 piezo positioning electronic On the back panel, there are: 1) voltage selector (100 / 115 / 230 V) with integrated fuse holder (see fuse description above), 2) main power switch, 3) main power supply connector, (IEC connector, 100 / 115 / 230 V, each +/- 10%, 50 / 60 Hz, max.
II.5. Pin Assignment II.5.a. Trigger Port The pin assignment of the 25 pin Sub-D connector (trigger port) as seen on the back panel of the electronics is given in the table below: Trigger Default Trigger Default Name Name Axis 1 UP Axis 1 DOWN Axis 2 UP Axis 2 DOWN...
Main Graphical User Interface III.2.a. Start-up Screens When starting the ANC300, the screen at first shows the logo screen fol- lowed by the initialization procedure. Then, the internal bus is scanned for present modules and their types. The type and the serial numbers are listed at their respective position. The sys- tem is then configured accordingly.
III.2.g. Limits Configuration Dialog In the limit configuration dialog, the user can activate certain limit set- tings per axis. Choose one of two limit sets, Room Temperature or Low Temperature. This setting allows choosing different limit settings for e.g. two different temperatures. Note .
III.3.a. ANM300 Front Panel Usage By turning or pressing any knob on a certain module front plate, the axis screen as shown in Figure 5 below will appear. Another way to get to the axis screen is to select the axis from the main overview list, or to cycle to the axis by clicking on the axis button repeatedly.
III.3.c. Stepping Functionality The stepping output signal is by default a sawtooth wave. See section IV.2.c on programming new patterns. One step corresponds either to a linear rise to the nominal voltage in time t = 1/frequency and a steep decrease to zero (on the order of 10 – 20 µs), or a steep increase to the step voltage and a linear decrease.
III.3.e. DC-IN Functionality There are two BNCs on the module frontplate, labeled DC-IN and AC-IN. The DC-IN input accepts -10 .. +10 V, while the output is (nominally) 0 .. +150 V. The gain is 15 (see Figure 6). Note. It is possible to input negative voltages on the DC-in of up to -10 V in order to pull down a positive offset voltage.
III.3.h. GND Functionality Upon pressing of the GND button, the ANM300 will disable all AC-IN, DC- IN, Stepping, and Offset functionality and will connect the outputs to chassis mass. Note. Connecting the piezoelectric actuator leads to a mass is important in order to reduce electro-mechanical noise on the actuator that might be produced by the electronics.
Hence, it is mandatory to measure the capacitance before applying any voltage to the outputs, in order to protect the ANC300 and the position- ers. Page 36...
III.4. ANM150 Module The ANM150 module is an open loop positioning module. The nominal output voltage is unipolar from 0 .. +150 V. The outputs are protected against short-circuits and have a current limiter in order to protect them. The following functions are available (see schematic graph below): Stepping with up to 150 V or up to 10 kHz rate (see section III.3.j on •...
III.5. ANM200 Module The ANM200 module is an open loop, low noise scanning module. The nominal output voltage is unipolar from 0 .. +150 V. The outputs are pro- tected against short-circuits and have a current limiter in order to protect them.

IV.1.d. RS232 Port The RS232 port on the backside of the ANC300 can be used to connect to a PC in order to establish a serial connection. The correct settings for the port are 38400 baud, 8 data bits, no parity, 1 stop bit, no flow control.

The time for each individual step is t= 1/256 * 1/f, with f being the chosen frequency. In the ANC300, the up and down patterns stored on each respective mod- ule can be modified individually. Figure 14: Default Up and Down Patterns.

In the same way, the output trigger values can be modified: > trig1.value = 1 This will set to output trigger no. 1 to high level (3.3 V). Set it to 0 again to commence the trigger pulse. The trigger object only has the .value property.

This example shows that in Lua it is possible to program functions and subroutines, which enables much more sophisticated possibilities than only calling single commands. The great advantage versus having a pro- gram running on a PC is that delays due to repetitive commands through the serial communication are minimized.

The serial number is given in Serial. The program determines whether a valid serial number was returned and writes this result to Serial OK. Data out is the direct response from the ANC300. ANC300_trigger_setget.vi ANC300_trigger_SetGet.vi reads and writes trigger status.
4. Login as user “update” with password “123456” (default). 5. Select binary protocol and upload the update file. 6. In case a mating update file is sent, the ANC300 will load and in- stall the update. During the update procedure, the ANC300 might restart once or twice.
After mains and all other cabling have been removed, open the cover of a free slot in the ANC300. Carefully insert the module taking care not to touch the electronics with bare hands to avoid damages due to static elec- tricity.
ANC300 in case the clicking cannot be stopped. Q) One axis of the ANC300 has no output and the red LED on one or more modules is blinking. A) The ANM modules feature overheat protection and shut down when too much heat is generated.
