Group 2: Operation Method Parameters

2-00Source of Master Frequency Command

		Factory Setting: d0
Settings	d0	Master Frequency input determined by digital keypad. (record the
		frequency of power loss and it can do analog overlap plus)
	d1	Master Frequency determined by analog signal DC 0V-10V
		(external terminal AVI). (won’t record the frequency of power loss
		and it can’t do analog overlap plus)
	d2	Master Frequency determined by analog signal DC 4mA-20mA
		(external terminal AVI). (won’t record the frequency of power loss
		and it can’t do analog overlap plus)
	d3	Master Frequency determined by Potentiometer on the digital
		keypad. (won’t record the frequency of power loss and it can do
		analog overlap plus)
	d4	Master Frequency operated by RS-485 serial communication
		interface and record frequency of power loss. (record the frequency
		of power loss and it can do analog overlap plus)
	d5	Master Frequency operated by RS-485 serial communication
		interface and won’t record frequency before power loss. (won’t
		record the frequency of power loss and it can do analog overlap
		plus)

This parameter sets the Frequency Command Source of the AC drive.

If the Frequency Command Source is external (DC 0 to +10V or 4 to 20mA), please make

sure the (AVI) terminal jumper is in the proper position as shown below.

Position of jumper: Please open the top cover. It is at the lower-left corner of the panel. The

jumper J1 determines the type of external analog input, either DC voltage signal or current

signal.

J1

Voltage signal input(0-10V)

Current signal input(4-20mA)

When setting analog overlap plus, it needs to set Pr. 2-06 to select AVI or ACI.
