The CFW900 is a high-tech VFD for driving and controlling three-phase induction and permanent magnet motors. It offers excellent static and dynamic performance and highly precise torque, speed, and position control. It can be used in a wide range of applications due to its high overload capacity. Thanks to its technology, the CFW900 variable speed drive provides energy savings, safety, increased productivity, and quality in the process network in which it is implemented. It allows quick and easy access to the application information and configuration settings. Using a menu structure, the new interface of the CFW900 line offers an unprecedented user interactive experience, providing settings and configurations with a detailed description of the parameters right on the HMI, in addition to event logs with date and time and a setup wizard.

More of Standard Features:

• IP20 Enclosure Protection class. (UL Type 1 with optional kit).
• Dual DC link inductors enable compliance with IEC 61000-3-2 & 61000-3-12
requirements regarding harmonics, (no need for external line reactance.)
• Normal duty and heavy-duty ratings to adapt to all kinds of loads.
• Conformal coated circuit board as per Class 3C2 in compliance with IEC
60721-3-3.
• Control Mode: Scalar, VVW (Voltage Vector WEG), Vector Control (Sensorless
and closed loop with encoder feedback), VVW PM (suitable for fan, Pump, and
compressor).
• Smart Thermal management allowing automatic adjustment of the switching
frequency to keep the motor running in adverse conditions of high temperature.
• IoT – Ready VFD with MQTT protocol allows direct integration with WEG MFM.
• Specific PWM Modulation function eliminates the need of an output filter up to
200m motor cable length.
• 4 independent slots with the possibility of expansion to 7 slots to accommodate
optional modules. (Any module can be mounted in any slot in any quantity, except
the communication module which is limited to one per drive.)
• Detachable Modern Text/Graphic Keypad with USB port, built-in Bluetooth
• (Bluetooth allows easy programming & and monitoring of CFW900 using
• Cell phone app “WEG WPS”), Real-time clock with event log, copy function,
Oriented start-up, and online help.
• Built-in as a standard:
– RFI filter meeting the requirements of electromagnetic compatibility directive
“EMC Directive 2004/108/EC”.
– Advanced SoftPLC (PLC functionality).
– 24Vdc power supply (max. 800 mA); can also accept external 24Vdc power to
keep control & communication circuits active.
– RS-485 (Modbus RTU) port
– Dual Ethernet ports (Ethernet/IP or Modbus TCP)
– STO (Safe Torque Off) and SS1 (Safe Stop, time controlled) safety functions
meet SIL3 & Ple / Category 4 requirements, eliminating need of Safety relay/
safety contactors
