1. INTRODUCTION
1.1. General information
This manual describes operations required for the installation and commissioning of the
HPD (High Performance drive) drive for brushless motors. Read all chapters of the manual
carefully before using the drive.
Peerlessness with previous versions: if you wire together the DC BUSes, the drive must be
of the same family (HPD with HPD, HPD N with HPD N - not HPD with HPD N !
Pay attention when ordering a spare part !).
Except the above situation, the
HPD N can replace a HPD drive.
When using the backup feature, DO NOT change the HPD N with the HPD: the
circuitry is different and the HPD requires the external relay.
1.2. Product description
The HPD drive is a digital frequency converter for driving AC brushless motors. The
adoption of a Parametric Operator Interface makes drive configuration procedures faster and
easier to repeat. The large number of configuration possibilities makes the drive suitable for
numerous applications.
A high power 16 bit micro-controller allows speed control with the characteristics required
of a servo controller, plus a range of auxiliary functions that can help reduce the presence of
control electronics in the application and thus permit considerable economic savings.
In addition to the positioner functions with trapezoidal profile, digital lock, spindle
orientation, stepper motor emulation, torque control and acceleration control, the HPD drive
also has an internal pico-PLC. The pico-PLC adopts the most diffused industrial
programming standards and offers considerable freedom for use of inputs and outputs. It also
enables users to develop a range of additional functions that are not among the basic features
of the drive.
The HPD drive is complete with an RS-422/RS-485 serial interface which can be used for
configuration, monitoring, or simultaneous transmission of commands to a multiple system
comprising up to 32 HPD drives.
In addition to the above functionality, the HPD drive is designed as an open system with
the facility to accommodate hardware and software expansion cards. For further information
on currently available expansion cards contact Parker Hannifin S.p.A. - S.B.C. Division
directly or your local Dealer.
