DI2 terminal function selection
DI3 terminal function selection
DI4 terminal function selection
DI5 terminal function selection
The functions of digital multi-functional input terminal DI1~DI5 can be set by parameter F1.00~F1.04.
The optional functions are shown in the following table:
The terminal for not use can be set to "no function" to prevent
accidental operation.
External terminals are used to control the FWD run mode of inverter.
External terminals are used to control the 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)
The setting of 16 stage speed or 16 kinds of other command can be
achieved through the 16 states of the four terminals.
Ac/deceleration time
selection terminal 1
The selection of 4 ac/deceleration times can be achieved through the
4 states of the two terminals.
Ac/deceleration time
selection terminal 2
Frequency source
switching
Used to switch between different frequency sources.
According to the setting of frequency source selection function code
(F0.07) , the terminal is used to switch between two frequency sources
UP/DOWN setting
(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.
When the command source is set to the communication control(F0.11
= 2), the terminal can be used to switch between communication
control and keyboard control.
Ac/deceleration
prohibited
Ensure the inverter is free from external signals affect (Except for
shutdown command), maintain current output frequency.
PID is temporarily disabled, the inverter maintains current output
frequency, no longer performs PID adjustment of frequency source.
When PLC pauses and runs again, this terminal is used to reset the
inverter to the initial state of simple PLC.
When the inverter outputs at center frequency. Wobbulate will pause
Input terminal of the count pulse
Input terminal of the length count.
If the terminal is active, the inverter switches directly to DC braking
status
External fault normally
closed input
When the signal of external fault normally closed input is inputted into
the inverter, the inverter will report fault Err.15 and shutdown.
If the function is set to be valid, when the frequency changes, the
inverter does not respond to frequency changes until the terminal state
is invalid.
PID action direction
as reverse
If the terminal is valid, PID action direction opposites to the direction
set by E2.03
External parking
terminal 1
Under keyboard control mode, the terminal can be used to stop the
inverter, same as STOPkey on the keyboard.
Control command
switch terminal 2
Used to switch between terminal control and communication control. If
the command source is selected as terminal control, the system will be
switched to the communication control mode when the terminal is
active; vice versa.
When the terminal is active, the PID integral adjustment function is
paused, but the proportion and differential adjustments of PID are still
valid.
Switch between frequency
source master setting and
preset frequency
When the terminal is active, the frequency source Ais replaced by the
preset frequency (F0.01)
Switch between frequency
source auxiliary setting
and preset frequency
When the terminal is active, the frequency source B is replaced with
the preset frequency (F0.01)
When DI terminal (E2.19 = 1) is used to switch PID parameters, if the
terminal is invalid, PID parameters use E2.13~E2.15; if the terminal is
valid, PID parameters use E2.16~E2.18
When custom fault 1 and custom fault 2 are active, the inverter
respectively alarms fault Err.27 and fault Err.28, and deals with them
according to the mode selected by the fault protection action F8.19.
If the terminal is valid, the inverter will park at the fastest speed, and
the current maintains at the set upper limit during the parking process.
This function is used to meet the requirements that the inverter needs
to stop as soon as possible when the system is in a emergency state.
External parking terminal
In any control mode (Keyboard control, terminal control,
