Chart 2-1 Wiring definition of NVBDH+ and NVBDL+
2.2 NVBDH+ connection
Thought parameter setting,the speed control mode can be adjusted by external analog
x
external PWM and panel potentiometer.Start/Stop also can be controlled by external interface or
panel keys,the use can define the combination control methods.Here we explain 3 ways
connection mode:Panel button speed Panel start/stop control
x
external analog speed
external interface start/stop control
x
external PWM speed external interface
start/stop control.Firstly introduce Hall version NVBDH+:
