3.7.7 I/O Signal Control and Functions
* “ON” expresses the bit signal of “1” and “OFF” expresses the bit signal of “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 instruction manual for the controller main body.
(1) Controller Ready (PWR)
When the controller can control the system after power up, it is turned “ON”.
„
Function:
Regardless of the alarm or servo conditions, when the controller initialization is completed normally
after power up 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)
When the controller is stopped in an emergency, it is turned “ON”.
„
Function:
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)
When any error is detected using the controller protection circuit (function), it is turned “ON”.
„
Function:
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, cycling the power is required).
When the alarm is detected, the Status Indicator LED (Refer to “3.3 CC-Link Interface”) on the front
surface of the controller illuminates in red.
(4) Reset (RES)
This signal has two functions. It can reset the controller alarm and cancel the reminder for planned
movements during pause conditions.
„
Function:
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, cycling 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.
