Delta’s intelligent C2000 AC motor drive and AFE2000 active front-end unit with their larger power and
energy-saving ability offer stunning performance for bridge crane applications.
Delta has built an excellent reputation in the industrial automation market for its AC motor drive technology and
continuous innovation. We have successfully developed our newest AC motor drive, the C2000 series. The bridge
crane application shows the C2000’s SVC control using the auto-tuning function to accurately obtain the motor’s
inductance value and resistance value. Precise calculation of slip deviation enables larger torque output for heavy
loads. Also, system stability is easily attained without speed sensors which makes the wiring for motor and drive less
complicated, and the control ratio is up to 1:100 (if the rated speed is 60Hz, the best speed control range is 0.6 ~
60Hz). This function is applicable to the treadmills, elevator doors, circular knitting machines and cranes.
The Delta C2000 provides sensorless vector control (SVC) to perform a nearly close-loop control function which
saves on purchasing an encoder and lowers maintenance cost. Compared with the traditional V/f control, the SVC
offers better performance for low speed operation, larger starting torque, and speed response to load increases and
decreases is faster. All these benefits allow cranes to activate easier for high friction and inertia load conditions. The
SVC control technology has been widely adopted for constant torque application. The Delta C2000 series AC motor
drive provides you with SVC control to overcome difficult crane start-ups at full load conditions.
Delta’s AFE2000 series active front-end unit not only improves electricity supply quality but also generates
re-usable energy to slow down global energy consumption. Delta’s mission has always been to provide innovative,
clean and efficient energy solutions for a better tomorrow. We are proud to launch our AFE2000 series which can help
you save up to 40% in energy use.
