Introduction

On a Variable Speed Drive such as Unidrive, timing functions necessary for
the correct operation of power devices are performed by its own
microprocessor operating in real-time. This imposes limitations on the
microprocessor when carrying out other duties, resulting in a reduction of
flexibility of the Drive.
To maximize this flexibility, a second processor can be used for running
application-specific software. This second microprocessor is the
which allows the Drive to be easily adapted to applications by programming
software in the

The DPL Toolkit is contained on two diskettes. It is a program which runs in
Microsoft® Windows™ Version 3.1x and Windows™ 95. Programs for the

The uses a high-level programming language called DPL
UD70
(Drive Programming Language) which is in many respects similar to the
BASIC language. DPL is a compiled program which gives it the ability to run
at high speed.
The DPL Toolkit is used to write, compile and download a DPL program to an
