Delta Electronics VFD-M Pr.47, Pr.48, Pr.49, Pr.50, Pr.51 Potentiometer Reverse Motion Enable

		Chapter 4 Parameters
Pr.47	Desired Frequency Attained	Unit: 0.1Hz
	Settings 0.00 to 400.0 Hz	Factory Setting: 0.00

This parameter allows monitoring a certain frequency and then activates one of the Multi-

function output terminals (Pr.45 or Pr.46 set to 8) when that frequency is achieved.

Pr.48	Adjust Bias of External Input Frequency
	Settings 0.00 to 200.0%

Unit: 0.1Hz

Factory Setting: 0.00 Hz

This parameter provides a frequency offset when the source of frequency command is the

analog input.

Pr.49	Potentiometer Bias Polarity
		Factory Setting: 00
	Settings 00	Positive Bias
	01	Negative Bias

This parameter sets the potentiometer Bias Frequency to be positive or negative.

Pr.50	Potentiometer Frequency Gain	Unit: 1%
	Settings 0.10 to 200.0%	Factory Setting: 100.0

This parameter sets the ratio of analog input vs frequency output.
