WEG CFW501 series is a compact variable speed drive designed for heating, ventilation and air conditioning applications.
It offers excellent efficiency and shares the same platform as CFW500, adding features such as fire mode, bypass, dry-pump and broken belt detection. It supports the most used communication protocols in the HVAC-R industry: BACnet, Modbus-RTU and Metasys N2, available in the standard product.
WEG frequency inverter CFW501 series special functions.
- Bypass:
Through one of its relay output the CFW501 and CFW701 allows the motor to be switched to the main power supply using additional components.
- Fire Mode:
This function makes the drive to inhibit its internal faults, making the motor run during adverse conditions without stopping the process.
- Advanced PID:
Three PID control loops: one controls the process 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 an external process not related to what the main PID loop is handling). This eliminates the use of an additional PID controller.
- Broken Belt Detection.
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 a programmed period of time. Wake-up mode determines motor restart conditions.
- Energy Saving:
Depending on the motor speed and load conditions, flux is reduced decreasing losses and improving efficiency. The future of our planet depends on conscious and sustainable actions and as the World’s population continues to grow rapidly, modern automated solutions are required.Technology is ever present in our lives, we have to find ways to efficiently produce the energy that drives all of these innovations.
- Dry Pump Protection:
Prevents the pump from running dry.
- PTC Monitoring:
PTC input terminals for motor temperature protection.
- Filter Maintenance:
Alarm Warns about the need to replace the filter.
- Short Cycle Protection:
It prevents loads like compressors from sucessives cycles of ON/OFF commands.
