4.14 Use of the PG Terminal
The closed-loop vector control with sensor (F0-01 = 1) helps to improve the speed stability
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.
• For the differential encoder, set F1-27 (Encoder pulses per revolution) and set F1-28 to
0 (ABZ incremental encoder).
• For the UVW encoder, set F1-27 (Encoder pulses per revolution) and set F1-28 to 1
(UVW incremental encoder).
• For the resolver, set F1-28 to 2 (Resolver).
• For the open-collector encoder, set F1-27 (Encoder pulses per revolution) and set F1-
28 to 0 (ABZ incremental encoder).
• For the wire-saving UVW encoder, set F1-27 (Encoder pulses per revolution) and set
F1-28 to 4 (Wire-saving UVW encoder).
4.15 Use of Serial Communication
When communication mode RS485, Profibus-DP or CANopen are adopted, you need
to install a corresponding extension card on the MD380 series AC drive, and set F0-28
correctly according to the used communication protocol type. CAN-link is enabled by default
and you need not select it.
For the conguration of hardware communication parameters for the communication port,
see group FD. Set the communication rate and data format to consistent with those of the
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.
