-246-
3: Three-wire operation control
This function is available only when the AC drive runs in three-wire control mode. To set a running
command through the terminal, set F4-17 (terminal control mode) to 2 (three-wire mode 1) or 3
(three-wire mode 2), and set this parameter to 3.
4: Forward jog (FJOG)
The terminal is used to set the AC drive to FJOG mode. The jog frequency, acceleration time, and
deceleration time are described respectively in F8-00, F8-01, and F8-02.
5: Reverse jog (RJOG)
The terminal is used to set the AC drive to RJOG mode. The jog frequency, acceleration time, and
deceleration time are described respectively in F8-00, F8-01, and F8-02.
6: Terminal UP
The terminal is used to increase the frequency when the frequency is set through the terminal. When
this terminal is active, it works as if the UP key is pressed and held.
7: Terminal DOWN
The terminal is used to decrease the frequency when the frequency is set through the terminal. When
this terminal is active, it works as if the DOWN key is pressed and held.
8: UP and DOWN setting clear (terminal, operating panel)
The terminal is used to clear the frequency set through the UP or DOWN key on the operating panel or
the terminal assigned with the UP/DOWN function (6 or 7), allowing the reference frequency to return
to the value of F0-08.
9: Fault reset (RESET)
The terminal is used to reset faults of the AC drive. Remote fault reset can be implemented by using
this function.
10: External fault NO input
When the terminal is active, the AC drive reports E15.01 upon receiving an external signal.
11: External fault NC input
When the terminal is active, the AC drive reports E15.02 upon receiving an external signal.
12: User-defined fault 1
When E27.00 is reported, the AC drive will take measures according to the value of F9-51 (fault
protection action).
13: User-defined fault 2
When E27.00 is reported, the AC drive will take measures according to the value of F9-51 (fault
protection action).
14 to 17: Multi-reference terminals 1 to 4
The setting of 16 speeds or 16 other references can be implemented through combinations of 16
states of these four terminals.
18 to 19: Acceleration/deceleration selection terminals 1 to 2
Totally four groups of acceleration/deceleration time can be selected through state combinations of
these two terminals.
20: Acceleration/Deceleration inhibition
The terminal is used to keep the AC drive at the current running frequency regardless of changes of
the external input frequency (unless a stop command is received).
21: Command source switchover terminal 1
When the running command is set through the terminal (F0-02 = 1) and this parameter is set to 21,
you can switch between terminal control and operating panel control by using this terminal. When
the running command is set through communication (F0-02 = 2) and this parameter is set to 21, you
can switch between communication control and operating panel control by using this terminal.
