 If you select P4 and P5 as an up-down drive terminal, select each 15 (frequency increase
command) and 16 (frequency decrease command) in the I20 and I21 of I/O group.
 If you select P3 terminal as an up-own save initial terminal, select 25 (up-down save initialization)
in the I19 of I/O group.
 Up/down Save function: If F63, „Save up/down frequency‟, is set to 1, the frequency before the
inverter was stopped or decelerated is saved in F64.

While up-down save operates, the user can initialize the saved up-down frequency by setting multi-
function input terminal as a up-down frequency save initialization.
F63 Save up/down frequency select 0 (Initial) Remove „save up/down frequency‟
1 Set „save up/down frequency‟
F64
Save up/down frequency
Up/down frequency saved

If „Up/Down Save Frequency Initialization‟ signal is input while the multi-function input „Up‟ or „Down‟
function is applied, this signal is ignored.

 Select 8 in Frq code of drive group
 Select the terminal which uses as a up-down drive from multi-function input terminals(P1~P5)
 Operates in selected mode as a step frequency set in F66.
 The up-down mode is Select as follows
F65 Up/down select
0
The reference frequency is increased according to
base of Max/Min frequency. (Initial value)
1
Increased as many as step frequency (F66) according
to edge input
2 Combination of 0 and 1
F66
Step frequency
Frequency increased according to edge input
 When F65 is 0: If you press UP, it is increased up to Max. Frequency as a speed set in the above. (If
frequency limit exist, speed is increased up to upper limit.) If press DOWN, It is decreased as a speed
