Roboteq's MBL1xxx is a features-packed, medium-currentsingle channel controller for brushless DC motors. Availablein 30V and 60V versions, the controller can operate in one ofseveral modes in order to sense the rotor position and sequencepower on the motors' 3 windings in order to generatesmooth continuous rotation. The controller also uses the Hallsensor and/or Encoder information to compute speed andmeasure traveled distance. The motors may be operated inopen or closed loop speed mode, position mode or in torquemode. The MBL1xxx features several Analog, Pulse and DigitalI/Os which can be remapped as command or feedbackinputs, limit switches, or many other functions. The MBL1xxxaccepts commands received from an RC radio, Analog Joystick,wireless modem, or microcomputer. Using CAN bus,up to 127 controllers can be networked at up to 1Mbit/s on asingle twisted pair.

The controller's operation can be extensively automated andcustomized using Basic Language scripts. The controller canbe configured, monitored and tuned in realtime using a Roboteq'sfree PC utility. The controller can also be reprogrammedin the field with the latest features by downloading new operatingsoftware from Roboteq.
