This parameter is used to set the functions of the digital multifunctional input terminal. The range is
as shown in the table below:
(When pulse input is selected for the frequency source, any function selected via DI4 will be invalid
and the pulse input will automatically be used.)
Setting value Function Description
0
No function
The inverter does not run even when there is signal. The unused
terminals can be set as “No function” to prevent error operation.
1
Forward running (FWD)
2
Reverse running (REV)
The forward rotation and reverse rotation are controlled via external
terminal.
3
Three-line running control
This terminal is used to confirm that the running mode of inverter is
three-line control mode. Refer to F3-00 for details on the introduction
of the three-line control mode.
4
Forward jog (FJOG)
5
Reverse jog (RJOG)
FJOG refers to jog forward running and RJOG refers to jog reverse
running. Refer to F6-04, F6-05 and F6-06 for details on the jog
running frequency and jog acceleration/deceleration time.
6
Terminal UP
7
Terminal DOWN
When the frequency reference is digital reference, increment
command and decrement command are modified via the external
terminal. The speed change is determined by F3-01 parameter and is
similar to the function of “” and “” keys on the keypad. The
selection of “0” and “1” via F0-02 determines whether the inverter will
store the setting.
8
Coast to stop
If the inverter output is locked, the motor stop is beyond the control of
inverter. It is often employed for the loads with high inertia and when
there is no requirement for the stop time.
This mode is the same as that described in F0-16.
9
Fault reset (Reset)
The external fault reset function. It is identical with the RESET key
and can be used to implement remote fault reset.
11
External fault input
When the external fault signal is sent to the inverter, the inverter stops
and reports fault.
12
Multi-speed terminal 1
13
Multi-speed terminal 2
The combination of digital status of the two terminals can realize 4
Multi-speed settings. Refer to the following chart for details on the
combination.

Acceleration/deceleration
time1 AND time2 switching
When the acceleration/deceleration switching function is selected, the
acceleration/deceleration time is 1 under normal condition. The
acceleration/deceleration time is 2 when the terminal is closed. The
acceleration time/deceleration time 2 also acts as the jog acceleration
time/deceleration time.
16
Potentiometer and AI
reference switching
Valid when potentiometer or AI reference is selected in F0-02.In this
situation, the switching between potentiometer and external analog
reference can be achieved.
