5.3.2 Internal input circuit

The signal state represents the "ON: Carrying current" or "OFF: Not carrying current" state of the internal
photocoupler rather than the voltage level of the signal.

E-STOP input
This terminal is used to input the emergency stop signal.
The E-STOP input is a normally closed. Input is enabled when the E-STOP is turned off, immediately
stopping pulse output and stopping the motor. The program stops, also.
In the normal state, be sure to connect the E-STOP input to GND to keep it on.
START input
This terminal is used to input the signal for starting the program.
The program is executed once the START input is turned on.
S-STOP input
This terminal is used to input the signal for stopping the operation.
The program is stopped once the S-STOP input is turned on. If the S-STOP input is turned
on while the motor is in operation, the motor will decelerate to a stop.
Once operation resumes, the program will start over from the beginning.
IN1 to IN8 inputs
General-purpose input terminals
M0 to M4 inputs
Terminals for choosing the program to be used through unique combinations of the M0 to M4 input
states. For more information about the selection of programs through combinations of M0 to M4
input states, see section 7.2, "Program execution via the host controller."
