INTROL MODEL 482 REGENERATIVE CONTROLLER
The Introl Design Model 482 is microcontroller based and offers the
latest in State of the Art Design. The Model 482 has been designed with the emphasis on
extremely fast response, for use in closed loop applications. Microprocessor design allows
excellent response characteristics while preventing excessive motor peak current. These
features make this control a viable low cost alternative, in many applications, to servo
amplifiers and motors. This control operates both permanent magnet and shunt wound motors.
In addition to closed loop control applications, this control operates exceptionally well
in standard variable speed and torque control (tensioning, unwind, re-wind, etc.) modes.
In torque control, the Model 482 can be programmed to deenergize the motor when a preset
speed is reached. This can be advantageous if a malfunction occurs (e.g. while tensioning
a material and the material breaks, the motor will accelerate to the predetermined speed,
then coast to a stop.)
