5.3 Group 2: Operation Method Parameters

2 – 00 A frekvencia parancs kiadásának forrása Factory Setting: d 0

Settings d 0 Master Frequency input determined by digital keypad.

(record the frequency of power loss and it can do analog

overlap plus)

d 1 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)

d 2 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)

d 3 Master Frequency determined by Potentiometer on the

digital keypad. (won’t record the frequency of power loss

and it can do analog overlap plus)

d 4 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)

d 5 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.
