The P1X_T is a programmable single-axis positioner with microprocessor and relay outputs that processes
signals supplied by incremental transducers such as encoders, magnetic lines, optical lines, etc.
The control of the positioning is made through the voltage analogue output, that may be set-up as 10/+10V or
0/10V or in current output 4/20mA. Other features are the relais outputs of Start/Onward/Backward, end of
positioning and the inputs of: Start, Emergency, Preset, Pieces-counter, all optoisolated.
The axis dimension is displayed on high brightness six-digit display (reading scale -99999, +999999) and three
auxiliary displays show the set dimension, the machine constants, and the processing parameters.
The keyboard with 16 keys and 8 function indicators make the positioner use and setting up easy.
The P1X_T can memorize up to 99 dimensions to create positioning programmes giving the possibility to
manage for every dimension the number of parts that are to be processed in sequence as well as the number
of cycle repetitions. In order to optimize positioning accuracy there are some parameters that can
counterbalance system inertia, clearances, and wear and tear of mechanical couplings.
Find below the other features characterising the instrument: automatic/semiautomatic, manual functioning
mode, absolute/line, single positioning, blade thickness compensation, zero research, inputs and outputs test;
and serial connection RS232 or RS485 with MODBUS RTU protocol to dialogue with remote units.
The keeping of data when there is no power supply is guaranteed by a non volatile EEPROM memory.
The instrument is enclosed in a panel box 72x144 conforming to the DIN 43700 standard.
