High-Performance Drives

WEG CFW500 ... New!

WEG CFW500 series drives are high-performance AC variable frequency drives that support closed-loop flux vector speed control as well as torque control modes and can operate both AC Induction motors and permanent magnet AC motors. These models are offered in an IP66/NEMA 4X enclosure up to 20 hp. Drives with high-performance features such as these have typically had long lead times, but now you can get them shipped direct from stock at AutomationDirect.com.

The CFW500 provides a broad range of input voltages and horsepower models to select from

• 200-240VAC 1-phase up to 3hp, 3-phase up to 10hp
• 380-480VAC 3-phase up to 20hp

Control Modes include Scalar, Vector Control (Sensorless and closed-loop with encoder feedback), and VVW PM (suitable for fan, pump and compressor)

• Speed and torque control down to 0 (zero) rpm & precision of 0.01% for speed control are attainable with closed-loop encoder feedback using vector control
• 0 to 500 Hz output frequency range
• 2.5 to 15 kHz adjustable switching frequency (5 kHz standard)

Advanced control features are available for applications where you need more than basic accel & decel.

• Speed and torque control down to 0 (zero) rpm & precision of 0.01% for speed control are attainable with closed-loop encoder feedback using vector control
• Linear and "S" ramp acceleration and deceleration
• Local/remote control
• DC braking
• Torque boost
• Motor slip compensation
• Electronic pot, preset speeds & Jog modes
• Adjustable V/Hz profile
• Maximum and minimum adjustable frequency limits
• Two skip frequencies
• Adjustable output current limit
• Flying start / ride-thru
• PID regulator & PID sleep mode
• AC Induction motors or Permanent magnet AC (PMAC) motor support

NEMA 4X (IP66) features

• For washdown applications and protected against high-pressure water spray from multiple directions
• Rated and suitable for use in direct sunlight, a unique feature not found often in VFDs
• Direct machine mount. This saves you money on additional enclosure space and shortens the length of your motor leads, which not only saves you money, but also lessens the severity of harmonics created by long leads that are damaging to motors

High-performance built-in features

• Built-in SoftPLC (Same programming software as other WEG VFDs CFW-WPS)
• Built-in RS-485 (Modbus RTU) communication
• Plenty of built-in I/O, expandable with option modules
• Built-in 24VDC power supply (max. 150 mA)

Optional Accessories and features

• STO - Safe Torque Off (TUV certified) with option module
• Keypad with backlight, with main display line, secondary display line and bar graph display
