Delta Electronics VFD-EL manual 02.19, User-defined Value

Chapter 4 Parameters

Use this parameter to change frequency when (1) Pr.00.13 is not set to 0 and frequency source is from communication or (2) Pr.02.10 is not set to 0.

02.19	User-defined Value 2		Unit: 1
	Settings	Read-only	Factory Setting: 0

For example: suppose that the frequency source is the first master frequency + second master frequency command (first master frequency is from keypad and second master frequency is from AVI), user-defined value 1 is set to 180.0(Pr.00.13 is set to 1800, Pr.00.14 is set to 1). AVI=2V=180.0/(2V/10V)=36.0, frequency is 36.0/(180.0/60.0)=12.0Hz

Pr.02.18=30.0, frequency is 30.0/(60.0/180.0)=10.0Hz

At this moment, the keypad will display 66.0(36.0+30.0) and the output frequency is 22.0Hz(12.0+10.0). When reading the value from communication address, the value will be shown as follows: 2102H and 2103H are 22.0Hz, 0212H(Pr.02.18) is 30.0, 0213H(Pr.02.19) is 66.0.
