Status LED and Status Output Signal

The G6000s include a Red/Green Status LED on their top (HVCPU) board that indicates the execution state of the controller. As a convenience, if the controller is embedded and the Status LED is not visible, the execution status can also be displayed by an external binary LED that is wired to the Status Output On/Off Signal Connector.

To configure the Status Output Signal Connector or any general-purpose digital output to serve as a status indicator, the "Power State DOUT" (DataID 235) must be set equal to the signal's GPL channel number.

The execution conditions that are indicated by the LED and the output signal (if configured) are described in Table 17-2. If Red or Green is not indicated as being on, they are off.

Table 17-2: Execution Conditions Indicated by LED and Output Signal
LED State	Status Signal	System Status	Description
Off, never on or blinking	Off, never on or blinking	Logic power off	Normally indicates that 24VDC logic power is off.
Green on, not blinking	Off, never on or blinking	Boot code loading software and firmware	Typically indicates that 24VDC logic power is on and the controller is executing its startup boot sequence. The Status Signal is off since the PAC files that control the Status Signal are being loaded.
Green blinks 1 time per second	Blinks 1 time per second	Normal operation, motor power off	The controller is executing in its standard operating mode and motor power is disabled.
Green blinks 4 times per second	Blinks 4 times per second	Normal operation, motor power on	The controller is executing in its standard operating mode and motor power is enabled.
Green blinks 8 times per second	Blinks 8 times per second	CPU overheating	The processor is overheating, motor power is off, and the user has 5 minutes to save any programs or data. After 5 minutes, the processor will shut down and needs to be rebooted.
Off, Green formerly blinking	Off, formerly blinking	Safety diagnostics failed	In rare instances, the green LED and the Status signal will be blinking for a period of time, but when a user attempts to enable motor power, both are turned off. This indicates that the robot's safety checks failed and the robot is not safe to operate.
Red on, not blinking	On or off, not blinking	CPU crashed	This rarely occurs and indicates that the controller has crashed due to a system hardware or software error.
