Single-axis positioner

The P_X positioning units serie are programmable microprocessor single-axis positioner with relay or analogue outputs that processes signals supplied by incremental transducers such as encoders, optical lines, and magnetic band (P1X-P2X) or provided by potentiometric position transducers linear or rotary (P3X). 
The opportunity to create customized working programmes makes them extremely versatile (cutting machines, bending machines, etc.). In order to optimise the accuracy of positioning there are the possibility to enter some parameters that are able to counterbalance system inertia, clearances, and wear of mechanical couplings. Positioning is managed through the Start/Stop, Onward/Backward, Slow/Quick, End of Positioning relay outputs. A voltage analogue output is also available that may be set up as -10 +10V or 0+10V as well as the 4÷20mA current output for the control of inverters or actuators. All of the positioner inputs Start, Emergency, Preset, Piece-counter, and counting inputs are optoinsulated.
➤ Other features: automatic/semiautomatic, manual, absolute/line working mode, memorization of 99 positioning dimensions with the possibility of programming the number of pieces to be worked in sequence and the number of cycle repetitions; test function to check inputs and outputs; RS232 or RS485 MODBUS RTU serial connection.
• P1X: the 16-key keypad and 8 operation indicators make operating and setup of the positioners user-friendly.
• P2X: programming is done very easily by four keys on the front panel; an auxiliary display allows a two character-driven programming in addition to displaying parameters during processing.
• P3X: processes signals provided by potentiometric position transducers linear or rotary. The 16-key keyboard with 6 operation indicators make it simple and easy to use and the setup of the positioner.

The transducers MT, MTV, MTP, the magnetic strip P50/10, the magnetic rings AM14 or AM20 are incremental systems without contact for linear or angular measures.
● Transducers MT (horizontal mounting) and MTV (vertical mounting) in shock-proof, self-extinguishing technopolymer; MTP (horizontal mounting) in aluminium case.
● Magnetic Band P50/10: the band consists of a magnetized plastic ferrite strip with alternate magnetic poles of 5 mm pitch, carried by a stainless steel strip-band. Mechanical protection of the plastic ferrite strip is supplied by a stainless steel band.
● Magnetic rings: AM14 with bore ø14, AM20 with bore ø20. Supported by an aluminium ring.
 for more complete information, see sec. "Absolute and incremental systems with magnetic band" in the drop-down menu on the left. 

EN14, EN20, EN25 are hollow shaft encoders that turn a rotating motion into codified digital pulses. A special feature is the easy assembling that carries out by introducing the hollow shaft into the drive shaft and locking it with a grain.
