Highlights Harmonic Mitigation with Inductor Meets the standard IEC 61000-3-12 in the

DC link built-in

PLC Function Built-In Programming flexibility combined with network and I/O make the CFW701 a

powerful part of an integrated system. Free WLP software in www.weg.net

RFI Filter Built-In Meets mandatory harmonic

Current standard EN 61000-3-12

HVAC Functions Bypass Using one of its relay outputs the CFW701 allows the motor to be started cross the line. External circuit is needed for this operation.

Fire Mode This function makes the drive inhibit its internal faults, making the motor run during adverse conditions without stopping the process.

Dry Pump Prevents the pump from running with no load.

Sleep / Wake-Up Mode Prevents the operation of the motor at low speeds for a amount of time programmed. Wake-up mode determines the time the drive is restarted.

HVAC Functions Short Cycle Protection Prevents a compressor / motor from being switched on and off in short periods of time.

Filter Maintenance Alarm Warns about the need to replace the filter.

PTC For monitoring PTC sensor.

Broken Belt Monitors motor torque and prevents the drive from running with no load in case of a broken belt.

HVAC Functions Advanced PID - 3 x PID Three PID control loops: one controls the process by itself (the one the motor is running) and two are additional PID loops for use to control independent process variables (it might be for the control of external process not related to what the main PID loop is handling). This eliminates the use of an additional PID controller.

Energy Saving Depending on the motor speed and load conditions, flux is reduced decreasing losses and therefore efficiency is improved.

Results

Energy Saving The future depends on conscious and sustainable actions as the world grows fast and for this, modern automated solutions are required. Technology is already present in our lives, and, in order to produce the energy that drives all the innovations, somebody has to foot the bill. What are you doing to grow sustainably? What are you doing to grow sustainably?

42% of the energy consumed worldwide today is used by industry.

68% of the energy used in industry is consumed by electric motors.

Energy Saving Save even more energy by using the CFW701 HVAC-R together with the W22 Premium motors, which have the best efficiency in the market. This solution can help you reduce power consumption by approximately 15%, thus contributing to sustainable development of the planet.
