NEL FREQUENCY CONTROLS INTRODUCES THE SMART ENCODER

Combines Encoder and Motor Control Circuit into One Unit

Burlington, WI   (March 21, 2005)   NEL Frequency Controls, Inc. announced today the release of its new Hercules Smart Encoder, which combines the encoder and motor control circuit into one unit to simplify the design of control loop motor controls. This innovative approach simplifies the task of interfacing between the motor, the encoder and the control.   Each Smart Encoder is programmed separately, according to the parameters provided for the individual application.

"The Smart Encoder simplifies the design task of the motor control circuitry," notes Chuck Ulland, Vice President of Sales and Marketing at NEL Frequency Controls.   "In most cases, all that is required is to provide the parameters to NEL, we program the Smart Encoder at the factory, and it is connected to the motor when it arrives."

The Smart Encoder can automatically adjust to maintain the motor speed via a pulse width modulated signal to modify the speed as there are changes in the motor load. It has a maximum shaft speed of 6,000 RPM, with bidirectional shaft direction and comes in standard shaft sizes of   3 / 8 " and 1 / 2 ". The enclosure is 2.5" in diameter, types NEMA 6P and IEC IP 67, with sealing in servo, flush or flanged mounting. Factory programming includes measurements for direction, distance, speed and/or acceleration of the shaft to which the Smart Encoder is connected. These settings can be changed by the user.
