Hello, I'm a field tech for an automation company. We're an integrator for Fanuc Robots.
I have a M20iA with a R30iA controller.
Today, when i arrived at the customer location, the system was faulted out. The robot was in the middle of executing a TP program to load parts.
All the IO files (labels and config) were lost, the OP screen we load into the pendant were also gone.
The robot is stuck in AUTO mode, and will not go into T1 mode. SYST-042 "deadman defeated" alarm is stuck active.
some other active alarms were
*SRVO-219
*SRVO-213
*SRVO-300
*SYST-042
I found the teach pendant cable pinched and had a small cut.
I replaced the teach pendant cable, swapped out the ESTOP board and tried a different pendant, and that cleared the 219,213 alarms.
Now, when i start up the robot, i get the DEADMAN DEFEATED, HANDBROKEN/HBK DISABLED, and TP enabled in AUTO mode, even when the pendant is OFF. And the robot is still stuck in AUTO mode.
After i reset the pendant, the only active alarm i have left with is SRVO-042.
The only thing i can think of now, is the CPU in the main slot1 is bad or the Amplifier is bad.
The system has been in production for about 8-12 months now.
Has anyone seen this problem before ?
I checked all the fuses in the Safety Card, and the new ESTOP board has new fuses.
Thank you in advance for any advice.
