Note:
1.
Apply NFB before power line input to inverter.
2.
The analog signal wires should be shielded & connected to the Earth.
3.
Refer to Sec.2.6, in order to select suitable discharging resistor.
4.
For models with P & N, must use separate Brake Discharge Unit and do not connect resistor to the P, N terminals
directly.
5.
To select Sink (NPN) type or Source (PNP) type by Jumper JP4 & JP5. Refer to section 1.2.3 & 1.2.4.
6.
Connect to DCOM if Sink (NPN) type selected; connect to 24V if Source (PNP) type selected.
7.
Connect to 24V if Sink (NPN) type selected; connect to DCOM if Source (PNP) type selected
