I/O signals
10 I/O signals
This manual describes I/O signals as follows.
•
Direct I/O: I/O to be accessed via I/O signal connector (CN2)
•
Remote I/O: I/O to be accessed via RS-485 communication
10.1 Direct I/O
Direct I/O is I/O that the I/O signal cable is connected to the I/O signal connector (CN2) to input and output signals
directly.
Assignment to the input terminals
The following signals are assigned at the time of shipment. Input signals and logic level settings assigned to the direct
inputs D-IN0 to D-IN4 can be changed using parameters.
Refer to p.58 for the input signals list that can be assigned.
Terminal name Factory setting
D-IN0 FWD (START/STOP)
*
D-IN1 REV (RUN/BRAKE)
*
D-IN2 STOP-MODE (FWD/REV)
*
D-IN3 M0
D-IN4 ALM-RST
*
If the 3-wire mode is selected with the "Operation input mode selection" parameter, the signal in the parentheses ( ) will be
applied.
Related parameters
Parameter name Description Factory setting
D-IN0 input function selection
Selects the input signal to assign to the direct input (D-IN0 to
D-IN4).
58: FWD (START/STOP)
*
D-IN1 input function selection 59: REV (RUN/BRAKE)
*
D-IN2 input function selection 72: STOP-MODE (FWD/REV)
*
D-IN3 input function selection 64: M0
D-IN4 input function selection 8: ALM-RST
*
If the 3-wire mode is selected with the "Operation input mode selection" parameter, the signal in the parentheses ( ) will be
applied.
Note
•
When the same input signal is assigned to multiple input terminals, the function will be executed if any one of the
terminals is turned ON.
(Except for HMI input, TL input, and EXT-ERROR input)
•
For the HMI input, the TL input, and the EXT-ERROR input, they are always being ON if not assigned.
If these signals are assigned to both direct I/O and remote I/O or to multiple terminals, the function will be enabled
when all terminals are turned ON.
•
For the direct input, in order to surely recognize the input signal, ensure the ON time and OFF time of each input
signal for at least 2 ms.
