Xx are 3 random terminals among X1-X8
defined as FWD, REV and 3-wire control function. K1 and K2 are invalid without connection of K3. After K3 is connected,
trigger K1, and the VFD runs forward; triggering K2 alone is invalid; trigger K2 after K1, the driver will switch its running
direction; disconnect K3, the driver will stop.

Notice
:
When forward running with 3-wire control mode 2, the VFD can reverse steadily only if the REV terminal is normally
closed, once disconnected of the terminal, the driver will runs forward.

This function code is used to setting the frequency modifying rate of UP/DOWN terminal, i.e. the changed value of
frequency when short-circuit UP/DOWN terminal with COM for one second.
When F0.18=1
(
high frequency mode
)
, the upper limit value of this function code is 500.0Hz/s.
