Precautions:
1. Multi-functional input terminal (X1~X8) can choose NPN or PNP transistor signal as the
input, the bias voltage can choose the inverter internal power supply (+24V terminal) or
external power supply (PLC terminal), factory value "+24V"and "PLC"are short
connected.
2. Analog monitoring output is for the specialized output of frequency meter, ammeter,
voltmeter, etc. Cannot be used for the control operations, like feedback control.
3. Due to the variety of pulse type in the actual use, the specific connecting mode should
refer to the detailed description.
