The following table lists the functions available for the DI terminals.
Table 6-1 Functions of DI terminals
Value Function Description
0 No function Set 0 for reserved terminals to avoid malfunction.
1 Forward RUN (FWD)
The terminal is used to control forward or reverse RUN of
the AC drive.
2 Reverse RUN (REV)
3 Three-line control
The terminal determines three-line control of the AC
drive. For details, see the description of P4-11.
4 Forward JOG (FJOG) FJOG indicates forward JOG running, while RJOG
indicates reverse JOG running. The JOG frequency,
acceleration time and deceleration time are described
respectively in P8-00, P8-01 and P8-02.
5 Reverse JOG (RJOG)
6 Terminal UP If the frequency is determined by external terminals, the
terminals with the two functions are used as increment
and decrement commands for frequency modification.
When the frequency source is digital setting, they are
used to adjust the frequency.
7 Terminal DOWN
8 Coast to stop
The AC drive blocks its output, the motor coasts to rest
and is not controlled by the AC drive. It is the same as
coast to stop described in P6-10.
9 Fault reset (RESET)
The terminal is used for fault reset function, the same as the
function of RESET key on the operation panel.
Remote fault reset is implemented by this function.
10 RUN pause
The AC drive decelerates to stop, but the running
parameters are all memorized, such as PLC, swing
frequency and PID parameters. After this function is
disabled, the AC drive resumes its status before stop.
11
Normally open (NO) input
of external fault
If this terminal becomes ON, the AC drive reports Err and
performs the fault protection action. For more details, see
the description of P9-47.
12 Multi-reference terminal 1
The setting of 16 speeds or 16 other references can be
implemented through combinations of 16 states of these
four terminals.
13 Multi-reference terminal 2
14 Multi-reference terminal 3
15 Multi-reference terminal 4
16
Terminal1 for acceleration/
deceleration time selection
Totally four groups of acceleration/deceleration time can be
selected through combinations of two states of these two
terminals.
17
Terminal2 for acceleration/
deceleration time selection
18
Frequency source
switchover The terminal is used to perform switchover between two
frequency sources according to the setting inP0-07
19
UP and DOWN setting
clear (terminal, operation
panel)
If the frequency source is digital setting, the terminal is used
to clear the modification by using the UP/ DOWN function or
the increment/decrement key on the operation panel,
returning the set frequency to the value of P0-08.
20
Command source
switchover terminal
If the command source is set to terminal control (P0-01= 1),
this terminal is used to perform switchover between terminal
control and operation panel control. If the command source
is set to communication control (P0-01= 2), this terminal is
used to perform switchover between communication control
and operation panel control.
21
Acceleration/Deceleration
prohibited
It enables the AC drive to maintain the current frequency
output without being affected by external signals (except the
STOP command).
22 PID pause
PID is invalid temporarily. The AC drive maintains the
current frequency output without supporting PID adjustment
of frequency source.
23 PLC status reset
The terminal is used to restore the original status of PLC
control for the AC drive when PLC control is started again
after a pause.
