Product Description
The PDHX15E is a single-axis packaged ministep drive incorporating an X150E position
controller. The PDHX15E-D is also available with a built-in regenerative dump circuit. The
drive is a chopper-regulated MOSFET design offering high performance in low and medium
power applications. The recirculating chopper regulator improves operating efficiency,
minimizes power consumption and reduces motor and drive heating. The drive is powered
Direct On-Line (DOL) from nominal mains supplies of 110V to 240V AC. An internal switch
mode power supply is used, incorporating power factor correction to minimise distortion of the
AC supply.
The PD-E series of drives have 4 selectable resolutions between 400 steps/rev and
4000 steps/rev, set using the front panel switches.They are suitable for use with EMC
compatible 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 lit up - see Maintenance and
Troubleshooting .
The drives can be used as stand alone units with separate control inputs and motor
connection/power inputs. The built-in controller performs position control and indexing
functions using an industry-standard RS232C interface, with RS485 communication as an
option. The programming language is based on Digiplan's X-code and the positioner is
capable of storing and executing complex motion programs from its non-volatile memory.
The drive 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.
EMC Directive compliance has been achieved through careful product design and does
involve the use of braided screen cables for the motor feed and controller inputs. However,
to maintain convenient interfacing no special cable screening requirements are necessary for
the user I/O connector, which may use standard equipment wire.
