Description
The P2X_T instrument is a microprocessor programming single-axis positioner with analog outputs that
processes signals supplied by incremental transducers such as rotative and linear encoders. The current
dimension is displayed with six digits and high brightness (reading scale -99999, +999999). The instrument
setting is obtained by means of four keys on the front panel; an auxiliary two digit display allows an assisted
programming and moreover it visualises certain parameters during working.
The control of the positioning is made through the voltage analog output, that may be set-up as -10/+10V or
0/10V or current output 4/20mA. Other features are the relais outputs of Start/Forward/Backward, End of
positioning, and the inputs: Start, Emergency, Preset, Pieces-counter, all optoisolated.
To optimize the accuracy of the positioning, P2X_T requires entering a few parameters in order to compensate
the inertia of the system, the clearances and the wear of the mechanical couplings.
Other features of the instrument are: semiautomatic/automatic, manual, absolute/relative and line working
modes, 99 positioning dimensions memory and possibility to program the number of pieces to be
manufactured in sequence and the number of cycle repeats; test function to check inputs and outputs; serial
port RS232 o RS485 (optional).
Data storage with the machine switched off is ensured by EEPROM memory.
P2X_T is built into a panel case 48X96 according to DIN 43700.

- Page 2 Input description The positioner is controlled by 4 opto-isolated inputs, that are: START: active from NA to NC, it causes the positioning start and brings different effects according to the working mode (see working mode at page 4). EMERGENCY: it must be normally closed, if open it blocks or interrupts the positioning PIECECOUNTER: at the end of each positioning the instrument expects a changing over of the piece counter input from NC to NA to proceed to the next positioning.
- Page 3 IMMEDIATE POSITIONING Immediate positioning mode allows you to set a positioning dimension to perform as soon as the START input is activated. Press to enter programming mode: on the display the writing will appear. RESET/ENTER the display shows the current dimension value, on the auxiliary display il display Press the writing “...

Select the first dimension of the positioning program by pressing the key and set its value according to the description of the previous paragraph. To control the inserted program you only have to enter the menu and run through the sequence of program steps: for the end of program dimensions the display will show the writing “...
- Page 5 • Duration of Positioning End Impulse (Cutting Time) Al At the end of the positioning, the positioning end output remains active for a period from 1 to 9999 milliseconds, according to the setting; the Setting 0 value at the end of the positioning output is always on. •...
- Page 6 • Preset Dimension The instrument enables you to set the value that will be visualised when the RESET/ENTER key is pressed or the PRESET input is activated, according to the zeroset mode you have chosen (see next paragraph). • Zeroset Modes By setting the Zeroset Mode you can determine the effect you will obtain by pressing the RESET/ENTER key for about 3 seconds or the effect of the PRESET input.

Page 7: Display Function
• Dimensions upper limit As for the previous constant, the positioner prevents the entry of dimensions exceeding the value set in this constant. Set a value upper then the maximum value of positioning dimensions • Display mode Setting this function gives the possibility to convert the quota visualized on the display in a quota expressed in inch fraction or degrees. -
Page 8: Test Function
TEST FUNCTION Enter programming mode and go to menu , press RESET/ENTER, insert password 273, confirm by RESET/ENTER and on the display will be shown 4 dashes witch correspond to the positioner inputs: the dash in the lower (upper) position means an open (closed) input. The Input test consists of closing the input switches and verify the correspondence between what is visualised on the display and the following picture: DISPLAY... - Page 9 POSITIONER OPERATING Once the instrument has been connected, set the machinery constants and insert dimensions and positioning programs as it is described in the previous paragraphs.
