Product Description

SL4 Series is high performance vector control Inverter, adopt 32-bits DSP control system,through decoupling control of flux current and torque current of motor, realize the fast response and accurate control of torque,can be widely used in situation where there is high demand for speed control accuracy, fast torque response,and low frequency high output torque.
 

Technical characteristics:

Three speed control methods:V/F control,open loop vector control SVC without PG,closed loop vector control FVC with PG

180% torque output at low speed,control accuracy ±5%FVC

Speed tracking restart function, to realize the smooth tracking and start without impact on the motor

Rich expansion card options:485 communication card,IO expansion card,PG card and other occupied expansion cards

2 types of field bus support: Modbus, CANopen

16-step speed,simple PIC,PID control and wobble frequency control

The accuracy of closed loop vector control with PG reaches ±0.1, provides 1:1000 speed control range

The panel adopts encoder for speed regulation,precised speed regulation
