ND300 Series General-Purpose VFD
The ND300 Series has fully digital designs with a core adopts 32-bit high-speed DSP. It has rich parameter settings, detections and perfect protection functions. It also has excellent control performances to adapt to harsh power grid environment.
The ND300 Series can be widely used as three-phase asynchoronous motor speed control system in various industrial fields, with high integration of characteristics such as flexible and diverse setting methods, programmable input and output terminals, standard communication bus and other festures into one.
Features
● Simple PLC, multi-speed operation: supports up to 16-speed operation
● Automatic voltage adjustment when grid voltage changes
● The key function can customize command channel switching, forward and reverse operation, inching operation and other functions
● Peripheral safety self-check on power-on: security detection of peripheral equipment on power-on can be realized
● Speed tracking restart: achieve smooth start of the rotating motor without impact
● Non-stop after instantaneous power outage: Use the energy from braking feedback to keep the motor running for a short time during an instantaneous power outage
● Multi-motor switching: two sets of motor parameters can realize switching control of two motors
● Built-in RS485 standard communication interface
● Multiple setting methods: operation panel, control terminal and serial communication
