Functions and Features

High reliability with the motor control IC+IGBT at the core

A wider tolerance for the changes of supply voltage by ±15% 

PID controller which is used in close loop control systems

Simple PLC which can achieve multi-speed, quasi winding and unwinding function, wobble, etc

High startup torque which can reach 150%while 1HZ

Good overload capacity which can reach 150% for 1 min, and 180% for 0.2 sec

Output frequency resolution can reach 0.01 HZ

Three user-defined frequency by passes and a range

Automatic compensate output torque when output frequency is low

Automatic regulate output voltage when supply voltage changes in range

Automatic energy-saving function which can automatic calculation the optimal output voltage

according to the load to save energy

JAROL communication protocol and modbus protocol, and it is easier for user to build up

centralized control system
