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 = H/H setting time
Panel frequency decremental gradient = H/H 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:
H = H =
(CEE (or H) /HJ)
(H/H setting time)
(FGE (or H) /HJ)
(H/H setting time)

Adjustment with pulse signals (Parameter-setting example 2)
Set parameters as follows to adjust the frequency in steps of one pulse:
H, H
Pulse ON time
H, H = Frequency obtained with each pulse
* The inverter does not respond to any pulses with an ON time shorter than set with H or H. 12ms
or more of clearing signal is allowed.
