DI1 terminal function selection
DI2 terminal function selection
The selectable functions are shown in the table below.
The terminal for not use can be set to "no function" to prevent
Accidental operation.
External terminals are used to control the FWD/REV run
mode of inverter.
Three-wire operation
control
This terminal is used to determine the inverter's three-wire
Control mode. For details, please refer to the instructions of
function code F1.10 ("Terminal command mode).
FJOG means Forward JOG running, RJOG means Reverse
JOG running. For Jog running frequency and Jog
Ac/deceleration time, please refer to the description of the
function code F7.00, F7.01, F7.02.
Modify frequency increment/decrement command when the
Frequency is referenced by external terminal. Adjust up/down
the set frequency when the digital setting is selected as the
frequency source.
The inverter output is blocked, at the time, the parking
process of motor is not controlled by the inverter. This way is
same as the principle of free stop described in F3.07.
The function make use of terminal for fault reset. It has same
Function with RESET key on the keyboard. This function can
be used to realize remote fault reset.
The inverter slows down and stops, but all operating
parameters are memorized. Such as PLC parameters,
wobbulate frequency parameters, and PID parameters. This
terminal signal disappears, the inverter reverts to the previous
state of running before parking.
External fault normally
open input
When the signal is sent to the inverter, the inverter reports
fault Err.15, and performs troubleshooting according to fault
protection action (for details, please refer to the function code
F8.17).
Ac/deceleration time
selection terminal 1
The selection of 4 ac/deceleration times can be achieved
through the 4 states of the two terminals. For details, see
Table 2
Ac/deceleration time
selection terminal 2
Frequency source
switching
Used to switch between different frequency sources.
According to frequency source selection function code
(F0.07) settings, the terminal is used to switch between two
frequency sources.
UP/DOWN setting
clear (terminal,
keyboard)
When the frequency reference is the digital frequency, this
terminal is used to clear the changed frequency value by
terminal UP/DOWN or keyboard UP/DOWN, so that the
reference frequency can recover to the set value of F0.01.
Run command switch
terminal 1
When the command source is set to the terminal control
(F0.11 =1), the terminal can be used to switch between
terminal control and keyboard control.
