For example, seeing is straightforward, but wading through the alarm history to find a "SRVO-050 Collision Detect" requires a specific sequence of key presses (often involving the F-keys and Shift combinations) that differ entirely from the later RJ3 or R-30iA controllers.
Since RJ2 is discontinued, official paper manuals are rare. Best sources: fanuc rj2 manual
If you are holding a FANUC RJ2 manual, or standing in front of a massive orange controller that hums with the sound of cooling fans and contains a proprietary tube-based CRT monitor, you are dealing with the industrial equivalent of a classic muscle car. For example, seeing is straightforward, but wading through
Modern robots have intuitive, touch-screen interfaces with color graphics. The RJ2, conversely, uses a monochrome (usually green or amber) text-based interface. The manual is essential for decoding the cryptic error codes that flash on the teach pendant. In the 90s, storing massive programs was difficult
In the 90s, storing massive programs was difficult. The RJ2 often used "Bubble Memory"—a non-volatile storage technology that was magnetically based and incredibly durable, but slow and expensive. If you wanted to run a program too large for the robot’s internal memory, you didn't use a USB stick; you had to set up (High-Speed Continuous Transfer).
