3.2.2 Control of Input Signal
The input signal of this controller has the input time constant of 6ms considering the prevention
of wrong operation by chattering and noise.
Therefore, input each input signal for 6ms or more
(Note 1)
continuously. The signal cannot be
identified if it is less than 6ms.
Note 1 It is necessary to input 26ms or more for PWRT Signal of PIO Pattern 1.
[Refer to 3.2.4 Operation with the Position No. Input = Operations of PIO Patterns 0 to 3]

1) The emergency stop status EMGS is turned ON when in normal condition and turned OFF
when EMG terminal on “2.1.3 [1] Power Supply Connector” is 0V (emergency stop
condition or disconnected).
2) It turns back ON once the emergency stop condition is released and EMG terminal goes up
to 24V DC.
Have an appropriate safety treatment such as interlock with this signal for the host
controller (PLC, etc.).
[Caution] EMGS is different from the emergency stop output caused by a controller alarm.
Caution: It is not an emergency stop output due to an alarm generation of the
controller.
