5.3 Description of Function Codes 5.3.1 F codes (Fundamental functions)
5-76
[ 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 E09
data = 17, 18)

 UP/DOWN control initial value selection
In addition to the reference frequency initial value when starting control, select the following operations.

Initial value of frequency setting when starting
UP/DOWN control

operation while the
inverter is stopped
0
Mode to fix to "0" [Compatible with previous
models]
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.
UP/DOWN based on selected
acceleration/deceleration time
Not possible
(fixed at 0)
1
This is the mode to set reference frequency at the
previous UP/DOWN control as the initial value.
[Compatible with previous models]
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).
The value in the memory is cleared by turning ON
digital input UP/DOWN frequency clear command
"STZ".
( Function code E01 to E09 data = 58)
Not possible
(previous value
held)
2
Mode used to fix to "0"
When resuming operation (including when power
turned ON), the initial value for the setting
frequency with UP/DOWN control is cleared to "0".
Increase the speed with the UP command.
UP/DOWN based on the following
tilt that is not dependent on
acceleration/
deceleration time
By turning ON UP or DOWN, the tilt
changes by 0.1%, and when
continuously ON, the UP/DOWN
operation is performed at change
rate of 0.1%/0.1 s or 1%/0.1 s.
100% indicates the maximum
frequency.
This operation is the same as
UP/DOWN control for PID
commands.
( Function code J02 data = 3)
Not possible
(fixed at 0)
3
Mode used to set reference frequency operated
with previous UP/DOWN command to initial value
The reference frequency can be increased or
decreased with the UP/DOWN command,
regardless of the inverter operating status, and
control is started from the reference frequency at
that point when operation is resumed (incl. when
power turned ON).
The value in the memory is cleared by turning ON
digital input UP/DOWN frequency clear command
"STZ".
( Function code E01 to E09 data = 58)
Allowed
The H61 factory default for this model is "3".
If using the UP/DOWN control function on previous models, operation corresponds to that of previous
models by setting "0" or "1" when replacing the inverter.
