2.7.7 I/O Signal Controls and Function
* ON indicates that the applicable bit signal is “1”, while OFF indicates that the bit signal is “0”.
The I/O control and functions used in the Position/Simplified Direct Value Mode, Half Direct Value Mode and
Full Direct Value Mode, are described as follows. For the I/O signals for the Remote I/O Mode and Remote
I/O Mode 2, refer to the Operation Manual for the controller main body.
(1) Controller ready (PWR) PLC input signal
When the controller can control the system after the power injection, it is turned “ON”.
عFunction
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
When the controller is stopped in an emergency, it is turned “ON”.
عFunction
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”.
(3) Alarm (ALM) PLC input signal
When any error is detected using the controller protection circuit (function), it is turned “ON”.
عFunction
When any error is detected and the protection circuit (function) is activated, this signal is turned “ON”.
When the cause of the alarm is eliminated and the reset signal is turned “ON”, the alarm is turned “OFF” in
the case that it is the alarm with the operation cancellation level.(In the case of the alarm with the cold start
level, re-injection of the power is required)
When the alarm is detected, the Status Indicator LED (Refer to 2.4, "CompoNet Interface”) on the front
surface of the controller illuminates in red.
(4) Reset (RES) PLC output signal
This signal has two functions. It can reset the controller alarm and cancel the reminder for planned
movements during pause conditions.
عFunction
[1] When this signal is turned ON from OFF condition after eliminating the cause of the alarm during the
alarm output, the alarm (ALM) signal can be reset.(In the case of the alarm with the cold start level,
re-injection of the power is required)
[2] When this signal is turned ON from OFF condition during the pause condition, the reminder of the
planned movement left can be cancelled.
