Adjustment with continuous signals (Parameter setting example 1)
Set parameters as follows to adjust the output frequency up or down in proportion to the frequency adjustment signal
input time:
Panel frequency incremental gradient = / setting time
Panel frequency decremental gradient = / setting time
Set parameters as follows to adjust the output frequency up or down almost in synchronization with the adjustment by
the panel frequency command:
= = 1
( (or ) /) ≦ (/ setting time)
( (or ) /) ≦ (/ setting time)

RUN command
Incrementing (UP)
Decrementing (DOWN) signal
Set frequency clearing signal
Upper limit frequency
Command frequency [Hz]
Lower limit frequency
Frequency 0 Hz
Adjustment with pulse signals (Parameter-setting example 2)
Set parameters as follows to adjust the frequency in steps of one pulse:
, ≦ Pulse ON time
, = Frequency obtained with each pulse
* The inverter does not respond to any pulses with an ON time shorter than set with or . 12ms
or more of clearing signal is allowed.
