Fuji Electric FRENIC-Ace series - 3 ] Frequency Setting by Digital Input Signal UP;DOWN (F01=7)

5.3 Description of Function Codes
5-54
[ 3 ] Frequency setting by digital input signal “UP”/“DOWN” (F01=7)
As frequency setting, UP/DOWN control is selected, and when the terminal command UP or DOWN is turned on
with Run command ON, the output frequency increases or decreases accordingly, within the range from 0 Hz to
the maximum frequency.
To perform frequency setting by UP/DOWN control, it is necessary to set the data of function code F01 to “7” and
assign “UP command [UP], down command [DOWN]” to the digital input terminals.
( Function code E01 to E05 Data = 17, 18)

Action
Data = 17 Data = 18
OFF OFF The output frequency will be held
ON OFF Increase output frequency by currently selected acceleration time
OFF ON Decrease output frequency by currently selected deceleration time
ON ON The output frequency will be held
■ UP/DOWN control initial value selection
Set initial value of reference frequency when starting UP/DOWN control.
H61 data Initial value of frequency setting when starting UP/DOWN control.
0
Mode to fix to “0”
When restarting operation (including when the power to the inverter is turned ON), initial
value of setting frequency by UP/DOWN control is cleared with “0”. Increase speed by UP
command.
1
This is the mode to set reference frequency at the previous UP/DOWN control as the initial
value.
The inverter internally holds the output frequency set by UP/DOWN control and starts to
control from the previous operation frequency at the next restart (including powering ON).
At the restart of operation, before the internal frequency reaches the previous output frequency, when
UP/DOWN command is input, output frequency at the point is held internally and UP/DOWN control
starts
from that value. Therefore, the previous output frequency data is overwritten and deleted.
