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)

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.
