DRV-28 inverter
s Basic operartion instructions
-93-
This parameter is used to set the corresponding function of digital multi-function input terminals.
Note: Two different multi-function input terminals cannot be set to the same function.

Description
0
No function
The inverter does not act even if there is signal input;
users can set the unused terminals to "no function" to
avoid misacts.
1
Forward running (FWD)
Control the forward/reverse running of the inverter by
external terminals.
2
Reverse running (REV)
3
3-wire control/Sin
Set the inverter running mode to 3-wire control mode by
this terminal. See P05.13 for details.
4
Forward jogging
Frequency when jogging, see P08.06, P08.07 and
P08.08 for jogging acceleration/deceleration time.
5
Reverse jogging
6
Coast to stop
The inverter blocks output, and the stop process of motor
is uncontrolled by the inverter. This mode is applied in
cases of large-inertia load and free stop time; its
definition is the same with P01.08, and it is mainly used in
remote control.
7
Fault reset
External fault reset function, its function is the same with
the STOP/RST key on the keypad. This function can be
used in remote fault reset.
8
Running pause
The inverter decelerates to stop, however, all the running
parameters are in memory state, eg PLC parameter,
wobbling frequency, and PID parameter. After this signal
disappears, the inverter will revert to the state before
stop.
9
External fault input
When external fault signal is transmitted to the inverter,
the inverter 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.
