As the computer revolution takes greater control of industrial processes, there is

a growing need for more intimate control of the process parameters. It is becoming ever more necessary to control the important characteristics of motors directly from computers and microprocessor- based controllers. Such control cannot wait for operator intervention when changes occur in milli- seconds and tolerances are measured in thousandths.

All of the operational characteristics of a motor are controllable by manipulating its speed, torque, and power. POWERTEC digitally implemented, speed, torque, and power control - the DFS-1.

The Brushless DC motor and its control are digitally based, and are a natural choice for a computer controlled environment. Now computers and PLC's talk to the drive itself when the field- installable DFS-1 control board replaces the Speed and Current boards on the standard POWERTEC Brushless DC drive.

One of the first things you will notice about the DFS-1 is that there are no adjustment potentiometers and no setup switches. All characteristics of the drive are controlled by software parameters which may be entered by the optional KDU-1 keypad or host computer. The KDU-1 keypad can be mounted on the DFS-1 board, in a remote location (usually the enclosure door), or in a handheld unit. A default set of parameters which represent the most common operating conditions will facilitate immediate operation and testing after installation.

Capable of operating on a single drive or in networks, the DFS-1 is programmable by an optional keypad with its two line, 16-character display. A single computer port may be used to monitor and control up to 32 units in an RS-485 communications link.

INTRODUCTION

Programmable analog inputs and analog outputs allow many possibilities for control through external voltages, currents, and frequencies. They may also be used to monitor drive operation. Digital inputs and outputs (also programmable) give control and monitoring flexibility as well as coordination functions.

Provision is made for plug-in options which add input and output options and accomplish special functions. Optional software packages may be ordered for specific application needs.
