Frequency converters EPV-VP series

Electric drive EPV-VP is used when it is necessary to ensure high accuracy of the motor torque or speed. To provide more accuracy motor control due to the high computing power EPV-VP electric drive can use the information from the speed sensor (encoder or resolver). There is a possibility to work without speed feedback in case of vector or scalar control. Typical fields of applications where high accuracy is needed: mode "master - slave" in multi electric motor drive system, the task of positioning and synchronize mechanisms, tension control for winders devices electric drives.

Advantages of the EPV-VP frequency converters

  • Static speed accuracy < 0,01%, depend on type of speed sensor
  • Possibility to work with incremental or absolute encoders
  • Operating voltage of encoder 5 V(RS422), 15 V or 24 V, depend on type of communication board
  • Full torque control in full speed range, zero speed included
  • Torque accuracy < 2%; < 5% for zero speed
  • Starting torque> 200%, depending on the engine power and converter
  • Built-in data collector for work analysis
  • Speed monitoring for several converters with PC
  • Possibility to create Master-slave systems
  • High-speed bus (12 Mbits) for high speed communication between frequency converters
  • High speed applications (up to 7200 Hz)
