Delta Electronics VFD-F Series 02-05, External Terminal, 00 2-wire #1, Fwd / Stop, Rev / Stop

VFD-F Series

The Carrier frequency of the PWM output has a signification influence on the electromagnetic noise, heat dissipation of the AC drive, and the acoustic noise to the motor as shown in the following chart.

Carrier	Acoustic	Electromagnetic	Leakage	Heat
frequency	Noise	Noise	Current	Dissipation
Signification	Minimal	Signification	Signification	Signification
Minimal	Signification	Minimal	Minimal	Minimal

When the carrier frequency is low, current ripple of the AC drive is large. This may result in a current display value greater than the actual value.

02 - 04	Forward/Reverse Enable		Factory Setting: 00
	Settings	00: Forward/Reverse enabled
		01: Reverse disabled
		02: Forward disabled

This parameter enables the direction of the AC drive.

02 - 05	2-wire/3-wire Operation Control Modes			Factory Setting: 00
	Settings	00: 2-wire (#1), FWD/STOP, REV/STOP
		01:	2-wire (#2), RUN/STOP, REV/FWD
		02:	3-wire

This parameter sets the operation mode when operating by external terminals.

Please refer to 02-01.
