POWERTEC DIGIMAX IV DIGITAL SPEED / RATIO Motor CONTROLLER

The DIGIMAX®is an advanced, micro-processor based, digital speed reference designed for use with POWERTEC Brushless motors and controls. It is a reliable and repeatable pulse train source with features designed for the needs of computer controlled process lines. It may be used for master speed setting or as an extremely accurate ratio

setting device.

The DIGIMAX®is an \"open loop\" type of control, i.e., speed feedback information to this speed setting device is not necessary to maintain the speed regulation of the system. The nature of the permanent magnet based Brushless motor and control system is that it will maintain zero percent speed regulation from no load to full load over its entire speed range. Closing the speed loop for speed regulation is unnecessary. Speeds

generated by the DIGIMAX®are accurate within 50 parts per million under all specified operating conditions. The Brushless motor will run at exactly the speed at which it is told to run, and the next time that same speed is commanded, it will be repeated exactly. The DIGIMAX®is as much at home in the ratio mode as it is in the speed mode, and it can switch between the two on the fly. This consistent speed control is invaluable in setting up processes which vary from day to day, but must be duplicated from order

to order. TheDIGIMAX®is also easy to apply and use. It can be installed in locations where it is easily accessible to operators, which may be remote from the location of the motor control. Control inputs and outputs are isolated, for flexibility and immunity to interactions between units.

Speed or ratio setpoints and operating parameters are entered via a 16-key keypad on the face of the DIGIMAX®. Speed or ratio setpoints and parameters may also be entered by remote connection to an industry standard RS-422 or RS-485 communications link with a variety of protocols. The five place digital readout may be set for motor RPM, process speed, or other useful engineering units, from the motor or from another source besides the motor being controlled. Indicators show when the speed is attained and whether the unit\'s control is local or remote.

The DIGIMAX®has six programmable output switches (open collector transistors), offering the possibility of operation completely through the communications link. There is a position registration function (temporary increase or decrease in speed) which may be alternatively programmed as a motor operated potentiometer. There are UP and DOWN controls are on the front panel, and there are remote inputs for these functions as well. The MOP function may be programmed to stay at its former speed after a stop, or to return to zero speed when stopped. DIGIMAX®represents a high level of sophistication for users of POWERTEC Brushless motors and controls. It is very effective in operator controlled or computer controlled systems when precision, repeatability, flexibility, and ease of interface to the host unit are required.
