accuracy of the AC drive. In this case, it is necessary to install an encoder for the motor.
Signals from the encoder are fed back to the AC drive through the PG card. The MD380
provides PG cards of four different types of signal features.
The AC drive supports four types of encoders, differential encoder, UVW encoder (wire-
saving UVW encoder), resolver, open-collector encoder.
The setting of encoder parameters varies with the actually used encoder type. Here takes
motor 1 parameters as an example for description.

4.15 Use of Serial Communication
When communication mode RS485, Profibus-DP or CANopen are adopted, you need

and you need not select it.

host computer, which is the precondition of normal communication.
The MD380 serial port itself supports the Modbus RTU slave communication protocol. You
can query or modify the AC drive's function codes, query various running state parameters,
and send running command and running frequency to the AC drive from the host computer
through the serial port.
