Elaborately Design ST100 Series Deft VFD

Elaborately Design ST100 Series Deft VFD

1,Larger rated current design, larger overload current and shorter acceleration time; 2,The over-excitation function is automatically added during the deceleration process, and the deceleration time is shorter; 3,Powerful overmodulation capability, higher output voltage with the same input voltage; 4,Powerful overload suppression to ensure that the inverter does not stop due to overload faults at maximum output; 5,Support Modbus/CanLink bus communication, easy to realize industrial automation networking; 6,Support CANlink bus mode and support synchronous control.
