3.7 Control and Functions of Input and Output Signals of Modes
Input and output signals are prepared for each axis number.
The applicable bit is “1” when the signal is ON and “0” when it is OFF.
3.7.1 Input and Output Signal Functions
[1] Controller ready (CRDY) PLC Input Signal

Regardless of the alarm or servo conditions, when the controller initialization is completed
normally after the power injection and the controller can control the system, it is turned ON.
Even in the alarm condition, when the controller can control the system, it is turned ON.
[2] Emergency stop (EMGS) PLC Input Signal
Operation
Mode
Positioner 1 Simple Direct Direct numeric

When the controller is stopped in an emergency (motor driving power is cut off), it is turned ON.
When the emergency stop status is cleared, it is turned OFF.
Also, ALM* in the driver status LEDs flashes. [Refer to Name and Function of Each Part 7)]
Have an appropriate safety treatment such as interlock with this signal for the host controller.
(Note) It is not an emergency stop output due to an alarm generation of the controller.
[3] Alarm (ALM) PLC Input Signal

This is a signal that is OFF in normal condition and turns ON when an alarm of operation
cancelled level
(Note 1)
or higher is generated. This signal turns OFF once the reset (RES) signal
is turned oON while an alarm of operation cancelled level is being generated. (In the case of the
alarm with the cold start level, re-injection of the power is required.)
Also, ALM* in the driver status LEDs flashes. [Refer to Name and Function of Each Part 7)]
Note 1 Check the 8.3 Gateway Alarm and 8.4 Driver Alarm for details of alarms.
