Overview

With a modern design and power ranging from 0.18 to 132 kW, the CFW500 frequency inverter is a high-performance VSD (Variable Speed Drive). The device offers sensorless vector, vector with encoder or scalar control modes, permanent magnet motor control, SoftPLC, which adds PLC (Programmable Logic Controller) functions, STO and SS1 Safety Functions, and selectable plug-in modules, providing a flexible and optimized solution for any application.

Main characteristics

• Output current from 1.0 to 211 A (0.25 to 175 cv / 0.18 to 132 kW);
• Single-phase or three-phase supply voltage 200-240 V or 380-480 V;
• Scalar Control (V / F), Vector Control (VVW), Sensorless Vector or Vector with Encoder Control, and Permanent Magnet Motor Control (VVW PM);
• Selectable plug-in modules;
• Plug and Play philosophy;
• Built-in operating and programming interface (HMI);
• Built-in RS485 port (in any selected plug-in module);
• Pump Genius: functions dedicated to driving pumps;
• Safety Function: STO and SS1 level SIL 3 / PLe;
• SoftPLC – built-in PLC functionalities;
• Braking IGBT (available from frame B);
• 3C2 or 3C3 protection class for application in environments with corrosive chemicals;
• IP20 (standard) and NEMA1 (optional) protection ratings;
• Fan with quick exchange system

Flexibility and Performance

The CFW500 has a modern design, and it can be selected according to the application requirements, providing flexibility with excellent performance. In the plug-in module version, the CFW500-IOS module comes with the VSD. In the version without plug-in module, the desired plug-in module may be selected (always one plug-in module per VSD). All plug-in modules have built-in RS485 Modbus-RTU.

The installation of the CFW500 is simple, and its configuration and operation is intuitive with the navigation menus of the operating interface (HMI) with built-in LCD display. Using the flash memory module, it is possible to download the existing setting from one CFW500 to other units without powering them up.

Connectivity

The CFW500 can be connected to the main fast industrial Fieldbus communication networks, with protocols used worldwide such as CANopen, Profibus-DP, EtherNet/IP, Modbus-TCP, PROFINET IO and DeviceNet, according to the plug-in module selected. In addition, all plug-in modules come with serial interface RS485 Modbus-RTU built-in.
