A new variable-speed ac motor speed control is simple to setup and operate. The rugged drive — Model 2999 Pacesetter AC speed control from Bodine Electric Co. — also features a NEMA-4X / IP-65 enclosure.
It’s suitable for stand-alone ac-gearmotor applications that need controlled acceleration, adjustable operating speed, or reversing. Typical applications include conveyor systems, packaging machines, food-processing equipment, medical or lab equipment and a wide range of other industrial automation equipment.
What kinds of motors can the Model 2999 control?
The rugged drive can control 230 Vac (50 or 60 Hz) inverter-duty, 3-phase gearmotors and motors rated up to 1 hp. It operates from a single-phase, 115 or 230 Vac line. Output is a sine-wave-coded pulse-width modulation (PWM) to get high motor efficiency and low noise. Users can adjust linear acceleration and deceleration … so can use the drive for soft-start applications.
The Model 2999 also has a built-in forward-stop-reverse switch to deliver dynamic braking where motors must be manually or infrequently reversed. User-friendly trimpots eliminate computer-like programming, and jumpers let users pair the drive with myriad motors without recalibration. The control is factory-set for most applications and is GFCI compatible.
The speed control allows for up to 200% starting torque, ensuring startup of high frictional loads. Slip compensation with static auto-tune and boost circuitry regulates load over a wide speed range. A run-fault relay signals when faults occur or if the drive is in stop mode, and can even turn off equipment. Circuitry protects against damage from undervoltage and overvoltage by shutting down the drive if AC input voltage goes out of range. Twin LEDs on the enclosure indicate power on and drive status. The control also has a start-stop switch and a main speed potentiometer.
Model 2999 dries are available through Bodine’s distributors, via direct OEM sales, or through the Bodine website. Stock orders typically ship within 2-3 business days.
