Delta Electronics VFD-EL manual Weights, 0=Active, 1=Off, 04.27

Chapter 4 Parameters

For Example:

If Pr.04.26 displays 52, it means MI1, MI2 and MI4 are active.

The display value 52= 32+16+4 =1 X 25+ 1X 24 + 1X 22 = bit 6 X 25+ bit 5 X 24 + bit 3 X 22

Weights							0=Active
Bit	1	1	0	1	0	0	1=Off
							MI1
							MI2
							MI3
							MI4
							MI5
							MI6

04.27	Internal/External Multi-function Input Terminals Selection		Unit: 1
	Settings	0 to 4095	Factory Setting: 0
	This parameter is used to select the terminals to be internal terminal or external terminal. You
	can activate internal terminals by Pr.04.28. A terminal cannot be both internal terminal and
	external terminal at the same time.
	For standard AC motor drive, the multi-function input terminals are MI1 to MI6 as shown in the

							MI3
							MI4
							MI5
							MI6

The Setting method is convert binary number to decimal number for input.

For example: if setting MI3, MI5, MI6 to be internal terminals and MI1, MI2, MI4 to be external terminals. The setting value should be bit5X25+bit4X24+bit2X22= 1X25+1X24+1X22= 32+16+4=52 as shown in the following.
