Analog Output Terminal Wiring
If the analog output terminal AO1 and AO2 are
connected with analog meter, it can measure
many parameters. The jumpers for AO1 and AO2
are CN16 and CN17.

Hint:
1. When using analog input, you should install
capacitor-filter or common-mode inductor between
VCI and GND, or between CCI and GND.
2. Analog I/O signals are sensible to interference,
ensure to use shielded cable and ground it properly.
The cable length should be as short as possible.

Serial Communication Port Connection
The drive can be connected to the host with
RS485 port directly.
Fig. 3-9 shows the connection of the drive with
the host with RS232 port.
Fig. 3-13 shows the connection of the drive to
PROFIBUS system via TDS-PA01 PROFIBUS
adapter.
Using above wiring method, you can build a
“single-master single slave” system or a
“single-master multi-slaves” system. The drives in
the network can be monitored, and be controlled
remotely and automatically in real time by using a
PC or PLC controller. Thus more complicated
operation control can be realized.
