Detailed Description

Vector control is also known as the "field oriented control", "flux oriented control" or "indirect torque control". Based on this latest motion control theory and technological achievement. PI8100 is sensorless vector control high performance frequency inverter (variable frequency drive). It achieves perfect motor control via servo function, and offers comprehensive drive solution.

Technical feature of this sensorless vector control high performance frequency converter:
1. Sensorless Vector control ariable frequency drive (variable speed drive, VSD, VFD) with high performance, excellent quality and low pollution
2. It achieves quick-response and precise control by decoupling control of motor magnetic flux current and torque current, which makes the speed adjustment and torque control runs at a high degree of accuracy and wide range.
3. Reasonable hardware platform, advanced processing technique and perfect testing equipment, which guarantees the applicable reliability

Brief Function Introduction on this vector control:
Central control module based on DSP, realizes high-speed and high performance control. Integrate V/F control, V/F+PG control (optional), vector control. Automatic recognize the parameter of the motor! Auto-adjust to the best control mode!
Dead zone compensate function, automatic slip compensate, 180% torque output can come out below 0.5 HZ frequency.
Eight switch inputs, three analog inputs, two analog output, 0-10V or 0-20mA from inside the scope of the definition signal!
Support feedback signal: 0-10v, 1-5v, 0-20mA, 4-20mA
Simple PLC Function, at most 15 segments speed control and 8 segments acceleration control can be realized.
Humanization display menu, highlighted OLED+LED, simultaneous display 3 groups of state parameters.
Hot-pluggable keyboard can restore or copy 4 groups of running parameter programs.
Powerful communication function which can support standard RS485 and Modbus and provide remote keyboard control .
Built-in PID self-adjusting
Rotate speed tracking start and power-off reset function
High effective function on default record and recheck, easy trouble -shooting.
Unique EMC design minimizes pollute to electricity resource.
Entire coating can work in various of severe environment.
Simplicity and fashionable design with industrialize features

Ratings:
