Adjustment with continuous signals (Operation example 1)
Set parameters as follows to adjust the output frequency up or down in proportion to the frequency
adjustment signal input time:
External logic input up/down frequency incremental gradient = f265 / f264 setting time
External logic input up/down frequency decremental gradient =
f267
/
f266
setting time
Set parameters as follows to adjust the output frequency up or down almost synchronously with the
adjustment by the external logic input up/down frequency command:
f264 = f266 = 0.1
(
fh
/
acc
)

(
f265
/
f264
setting time)
( fh / dec )

( f267 / f266 setting time)
<<Sample sequence diagram 1: Adjustment with continuous signals>>
The dotted line denotes the output frequency obtained by combining the slowdown speed and the
panel frequency adjustment speed.

■
Adjustment with pulse signals (Operation example 2)
Set parameters as follows to stepwise adjust the frequency by one pulse:
f264 , f266  ≤ Pulse On time
f265 , f267 = Frequency obtained with each pulse
* The inverter does not respond to any pulses with an ON time shorter than that set with f264 or
f266 . 12ms or more of clearing signal is allowed.
