Function
The terminal is used to determine the three-wire running control of
(Sln) the VFD. For details, see the description for P05.12.
Jog forward
For details about frequency of jogging running and ACC/DEC time of
jogging running, see the description for P08.06, P08.07, and P08.08.
The VFD blocks output, and the stop process of motor is uncontrolled
by the VFD. This mode is applied in the scenarios with large-inertia
loads and without stop time requirements.
Its definition is the same as P01.08, and it is mainly used in remote
control.
External fault reset function, same as the reset function of the
Fault reset STOP/RST key on the keypad. You can use this function to reset
faults remotely.
The VFD decelerates to stop, however, all the run parameters are in
memory state, such as PLC parameter, wobbling frequency, and PID
parameter. After this signal disappears, the VFD will revert to the
state before stop.
When external fault signal is transmitted to the VFD, the VFD
releases fault alarm and stops.
Used to change the frequency increase/decrease command when
(UP) the frequency is given by external terminals.
The terminal used to clear frequency-increase/decrease setting can
clear the frequency value of auxiliary channel set by UP/DOWN, thus
restoring the reference frequency to the frequency given by main
reference frequency command channel.
The function is used to switch between the frequency setting
and B setting
channels.
A frequency reference channel and B frequency reference channel
can be switched by function 13; the combination channel set by
setting
P00.09 and the A frequency reference channel can be switched by
function 14; the combination channel set by P00.09 and the B
frequency reference channel can be switched by function 15.

A total of 16-step speeds can be set by combining digital states of

these four terminals.
Note: Multi-step speed 1 is the LSB, and multi-step speed 4 is the
2
MSB.
