6
Coast to stop
The VFD blocks output, and the stop process of motor is
uncontrolled by the VFD. This mode is applied in cases of large-
inertia load and free stop time; its definition is the same as
P01.08, and it is mainly used in remote control.
7
Fault reset
External fault reset function; its function is the same as the
STOP/RST key on the keypad. This function can be used in
remote fault reset.
8
Running pause
The VFD decelerates to stop, however, all the running
parameters are in memory state, e.g. PLC parameter, wobbling
frequency, and PID parameter. After this signal disappears, the
VFD will revert to the state before stop.
9
External fault input
When external fault signal is transmitted to the VFD, the VFD
releases fault alarm and stops.
10
Frequency increase (UP)
Used to change the frequency-increase/decrease command
when 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.

Switching between A setting
and B setting
This function is used to switch between the frequency setting
channels.
A frequency reference channel and B frequency reference
channel can be switched by no. 13 function; the combination
channel set by P00.09 and the A frequency reference channel
can be switched by no. 14 function; the combination channel
set by P00.09 and the B frequency reference channel can be
switched by no. 15 function.

Multi-step speed terminal 1
16-step speeds can be set by combining digital states of these
four terminals.
Note: Multi-step speed 1 is low bit, multi-step speed 4 is high
bit.
