Method of application:
Configure the parameters according to section 4.1 "Commissioning instruction for the dual-VFD air
compressor", as shown in the following table. You can realize the dual fan system of main motor
frequency conversion, in which U1, V1, and W1 terminals of GD300-01A-RT VFD can be used to
realize variable-frequency fan output, and U2, V2, W2 terminals can be used to realize power
frequency fan output.
