Applications involving high inertia loads, when applied short time deceleration, a large amount of energy returns from the motor to the VSD. To handle this energy, reguilar VSDs have to dissipate it as heat in power resistors. Such resistors are usually large and some installation criteria must be considered due to their heat dissipation. As an alternative to the use of braking resistors, CFW11 features a special braking method in vector control mode known as Optimal Braking. This innovation delivers a high performance braking torque without requiring a braking resistor. The following graph shows the advantages of using Optimal Braking compared to other braking methods, thus ensuring an optimized and low cost solution for braking applications.

Linear and adjustable V/F, VVW (Voltage Vector WEG) and vector control are available on CFW11
Two types of vector control: sensorless and closed loop vector control (encoder Interface required)
Sensorless vector control permits high torque and quick response in open loop, even at low speeds
The self-tuning function sets the vector control or VVW with the motor and to application load used
By the adjustable V/F control, it is possible, for example, to adjust a quadratic V/F curve, providing energy savings for quadratic torque loads (e.g.: centrifugal pumps and fans)

New 40hp motor

Verified · SKU 1312372

We had our 40hp compressor go down. We determined over the weekend that a motor winding was bad. First think Monday morning I consulted with the techs at MRO and verified that the manufacturer had a replacement in stock so I placed the order. The new motor (600 lbs) arrived on Wednesday... WOW. Granted the motor was in Georgia and we are in Tennessee but still the service and speedy delivery was incredible! Read more
