4. Operation
4.3 Pulse Train Control Mode
4-104 ME0342-4B
4.3.2 Operation Ready and Auxiliary Signals
[1] System Ready (PWR)
PIO signal
The signal is turned ON if the controller can be controlled after main power-on.
It is turned ON once the initialization terminates normally after main power-on and PCON can
be controlled regardless of alarm and servo status.
Even in the alarm condition, when the PCON can control the system, it is turned “ON”.
[2] Emergency Stop Status (EMGS)
PIO signal
1) The emergency stop status EMGS is turned on when in a non-emergency-stop state and
turned off when EMG terminal on [3.1.3 [1] Power Supply Connector (for Power Supply and
Emergency Stop)] 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
● It is not an emergency stop output due to an alarm generation of the controller.
[3] Operation Mode (RMOD, RMDS)
PIO signal
Two operation modes are provided so that the operation by PIO signals does not overlap with
the operation by a teaching tool such as PC software through SIO communication.
The mode change is done by the operation mode setting switch on the front panel of the
controller.
AUTO ········Operation by PIO signals is valid.
MANU ········Operation through SIO communication is valid.
