The PDX series of single-axis packaged ministep drives consists of the PDX13 and PDX15, with peak current ratings of 3A and 5A respectively. A further 5A version, known as the PDX15-D is also available with a built-in regenerative dump circuit. PDX series drives are high-performance, MOSFET, chopper-regulated stepper drives designed for optimum performance in low and medium power applications. A recirculating chopper regulator improves operating efficiency, minimizes power consumption, and reduces motor and drive heating. They are powered from direct on line mains supplies of 110V to 240V (nominal) AC. An internal switch mode power supply is used, incorporating power factor correction to minimize losses in the AC supply.
PDX drives incorporate an RS232C-programmed indexer, which features a complete range of motion control commands using Digiplan's X-Code command language. Its non-volatile memory may be programmed with up to 7 complete motion control sequences which can be selected using external input signals. The indexer has dedicated inputs for home-position and end-of-travel limit switches, with provision for 3 programmable user inputs and 2 programmable outputs. Hardware addressing allows up to 8 drives to be connected to a single serial port and up to 255 drives when software addressing is used. The drives are suitable for use with hybrid and permanent magnet stepping motors having 4, 6, or 8 leads. Motor short-circuit protection is assured across and between phases and between any phase and earth. If a wiring fault occurs the drive fault LED will be illuminated. The drive, indexer and integral power supply are contained in one compact enclosure, cooled by natural convection. Wall or panel vertical mounting is recommended to allow access to the front panel connectors and controls for service personnel use.
