WEG CFW -701 Series

• 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.
• 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 controlling 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.
• Broken Belt– Monitors motor torque and prevents the drive from running with no load in case of a broken belt.
• Sleep / Wake-Up mode– Prevents the operation of the motor at low speeds for specific programmed time. Wake-up mode determines the time the drive is restarted.
• Dry Pump– Prevents the pump from running with no load.
• Filter Maintenance Alarm– Warns about the need to replace the filter.
• Short Cycle Protection– Prevents a compressor / motor form being switched on an off in short periods of time.
• 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.
