The improvements of S200 Series inverter are as below:
1) Anti-interference performance improved.
2) Supporting 4 extension card, stronger extension function
3）Communication extension card is support,communication reliability is higher.
4）S200 series frequency inverter improves the lightning protection performance .DC fan and DC contactor adopted improve the system reliability;All have DC bus power supply function ,can be used in EPS directly.
5）Two relay output,two analog FM output.
Stable Control Mode
(1) VF control: Multiple curve could been chosen, Linear V/F curve, 2.0 times power drop torque V/F curve, custom V/F percentage(can implement manual energy saving control), multipoint VF curve. This apply to the situation that one frequency inverter drives multiple motors, such as fan, water pump, engraving machine, injection molding machine etc.
(2) Open-loop vector control: Steady speed with high precision, wide range of speed governing, as the speed ratio is 1:200 and frequency is 0.5Hz, we could output 180% rated torque. Good dynamic performance.
Open-loop vector is suitable high-Performance universal occasions such as machine tools, centrifuges, cranes and handling equipment, rolling mill and other loads.
(3) Torque control: Fast torque response, <20ms, precision torque: <5%, applied to winding, drawing and other occasions.
(4) Double row shows to monitor the frequency and current at the same time.
