General Variable Frequency Drive Specifications

VFD Control Features
  • Open loop vector control variable frequency drive
  • Speed or torque control variable frequency drive
  • Speed reference input: 0-10V, 0-20mA, 4-20mA, (-10 to +10V SM-I/O Lite option)
  • 4 digital inputs- World (enable, run forward, run reverse, local/remote)- USA (not stop, run, jog, local/remote)
  • VFD switching frequency: 3 (default) – 6 – 12– 18 kHz
  • VFD Output frequency 0 to 1500Hz
  • VFD Accelerate and Decelerate ramps (linear and S type)
  • Positive logic control
  • Serial communication - Modbus RTU RS485 via RJ45 connector- Baud rate 4800, 9600, 19200or 38400 bits per second
  • DC injection braking as standard in the VFD
  • Dynamic braking transistor as standard in the VFD
  • Dynamic motor flux V/Hz for energy saving
  • Quadratic motor flux V/Hz for fan and pump optimization
VFD General Characteristics
  • VFD maximum overload 150% of rated current for 60s
  • Intelligent Thermal Management (ITM) optimizes switching frequency
  • 8 preset speeds in the VFD
  • Flying start
  • Mains dip ride through
  • Automatic no-spin autotune for fast performance optimization
  • VFD's keypad access to all parameters for more demanding parameter settings
Environment
  • NEMA 1 rating with optional cover
  • Ambient temperature -10 to +40°C @ 3kHz switching
  • Humidity 95% maximum (non-condensing)
  • Electromagnetic Immunity complies with EN61800-3 and EN61000-6-3 and 4
  • Electromagnetic Emissions complies with EN61800-3 (second environment) as standard. Complies with EN61000-6-3 (residential)and EN61000-6-4 (industrial) generic standards with optional footprint EMC filter

Protection
