The electronic control unit uses a high-performance microprocessor, optimised for motor control. Closed loop speed control is implemented using a proportional plus integral (PI) algorithm. Speed ranges are 33.3, 45 & 78 rpm, with fine pitch speed adjustment allowing increments/decrements of +/-0.01% of the selected speed.
The electronic control circuitry and power supply unit are housed in an external one-piece CNC machined case. This new design offers complete isolation and support and is the perfect environment for the electronics. Speed selection controls are mounted on the front facia panel with LED indicators.
