EM-106 BRUSHLESS DC-MOTOR CONTROL UNIT 12-24V 5A FEATURES: • Three phase output • Direction change • Hall-transducer supply and input • Supports 60° and 120° commuting • Adjustable current limit • Direct or freq.locked driving • High efficiency • Inbuilt fuse • Rail mounting base available EM-106 controller is designed for brushless hall-feedback DC-motors. The device uses mosfet-type power stage with high efficiency. EM-106 can be connected to 60- or 120 degrees commuting motor. Standard driving includes speed adjustment, stopping, direction change and braking. The controller can be installed using screws or a standard rail mounting base. There are two control modes: Within direct driving mode the motor voltage is set in proportion to the control voltage as with a normal DC-motor. Alternatively in frequency locked mode the controller uses the halltransducer signal to speed adjustment besides commuting. This mode gives very precise speed referenced to the control voltage. As an additional feature the controller has an adjustment for loop response so that it provides as stable control as possible within all applications. Control input can be scaled with a trim. The current limit is set with a trim, it restricts driving when motor current exceeds the given value. The controller is protected against reversed input voltage polarity and fuse protected against over current.

EM-106 OPERATING INSTRUCTIONS Operating voltage 12-36V filtered, less than 20% ripple. Speed control set with voltage or potentiometer. Range is adjustable with SCALE and ZERO trim. Speed control mode NORMAL or CLOSED LOOP is selected with SW1. Normal speed control: Motor acts like normal DC-motor without feedback. Closed loop control: The control unit uses a hall sensor signal to regulate motor speed. Accuracy of motor rpm is typically ±1% in this mode. The desired rpm range in closed loop mode is selected with SW3. Synchro control: A SYNCHRO OUT feature can be used if phase locking loop...
