Rexroth Frequency Converter VFC

Rexroth VFC 3210, 3610 & 5610 series has been especially developed to meet the requirements of emerging markets.


VFC 3210

VFC 3210

Rexroth VFC 3210 with enhanced V/f control, covering the power range from 0.4 to 4 kW, is a multifunctional mini type frequency converter. It is widely used in the fields of woodworking machinery, packaging machinery, food processing and HVAC due to its characteristics like side by side mounting, smaller depth than VFC 3610, free cooling (up to 1.5 kW), built-in PID, multi-speed control and torque compensation etc.

Smart & Delicate

  • Nearly 30 % decrease in depth than 3610 to better adjust to customer installation requirements. 
  • A super mini type in compact design. 
  • Side by side mounting. 

Superior Performance

  • The high starting torque of 150 % 3 Hz and 100 % Hz 1.5. 
  • Over-excitation control to reduce the braking time. 
  • The capacity overload of 150 % 60 s. 
  • Modbus RTU is standard. 
  • PC software and firmware updates (via Mini-USB port). 

Easy to Operate

  • Built-in LED operating panel. 
  • Easy to operate and maintenance, removable fan, free cooling (not more than 1.5 kW). 
  • Structured parameter group for convenient commissioning. 
  • Automatic speed limiting and capture. 

Stable & Reliable

  • Systematic safety standard and reliability test system. 
  • Complete converter protection (phase failure, interphase short circuit, the earthing short circuit, overcurrent, overvoltage, under-voltage, overload, overheat and overheating protection for motors). 
  • Reinforced coating of circuit boards for dust-proof and anti-corrosion.
