The wiring mode of the control circuit of the frequency converter is shown in the figure on the following:

Notice: 1 Terminal : Indicates the main loop terminal.Indicates the control loop terminal;

2 Signal cables and power cables must be routed separately, and the control cables and power cables should be crossed at a 90-degree Angle as far as possible.The analog signal line reference diagram describes the selection of linear, power cable is the best choice of shielded.

 

Multi function contact input connection

Multifunctional digital input terminals support NPN or PNP connection type. DI1 terminal is flexibly connected to external devices. You can select the NPN or PNP mode through the jump cap at J27 on the control board (the factory default mode is NPN). Connection mode of NPN characteristic transistor:

 

Precautions: If the external power supply is connected in NPN mode, remove the jump cap in position J27. Connection mode of PNP characteristic transistor:
