The virtual COM converts the data sent to RS-232 port into Ethernet. Virtual COM only

connects to software supporting serial ports, e.g. Delta WPLSoft, VFDSoft, ASDASoft. See

the examples below for how to connect VFD-E series AC motor drive to VFDSoft through by

virtual COM.

Steps

(1) Select user-defined protocol and set the communication parameters for serial

master/slave to the same as the parameters in VFD-E.

(2) Set up virtual COM.

(3) Open Delta VFDSoft, set up the communication format and establish the connection.

 Select Virtual COM for COM2 mode (RS-485) and set up the same communication parameters as

those in VFD-E.
