The BLF series brushless DC motor system adopts a new design for its motor, gearhead, and driver. High performance speed control is achieved with an increased speed range of 80 to 4,000 rpm (50:1). In addition, the BLF series is IP65 rated providing splash and dust protection. The BLF series driver introduces a detachable digital operator unit that serves both as a data input unit and a digital display that can be used up to 16.4 ft away from the installed driver. The user can program eight separate speed levels. Each speed can be set in units of 1 rev. per minute with separate acceleration and deceleration values. Detection of various motor and driver error functions including overload, overvoltage, low-voltage, missing phase, overspeed, overcurrent, etc., will immediately stop the motor and output an alarm signal.
