Yasnac MRC Alarm 120, encoder communication error

Yaskawa does not support MRC any more. It's hard to say what the problem is because we don't know what axis this alarm comes up on and what size robot arm you have. Was the robot working before you initialized it?
-
PG stands for pulse generator - another way to refer to an encoder, so to speak. The K3 arm was actually migrated over from the ERC platform from the late 1980s and early 1990s. I hope you have some spare parts for it as they are very hard to come by. Enjoy your robot!

To load programs into the controller or save programs from the controller to a computer, you will need to purchase FDE (Floppy disk emulator) for Windows. This software will probably still be available and purchasable from your local Yaskawa representative.
With respect to the pendant, be aware that there were 2 versions of pendant sold with MRC - one with deadman switch, one without. Not sure which one you are working with, or if the two pendants you have are the same.
Good luck!

The Pendant has no dead man switch, it uses a green button for servo on, see below:
Will look around on FDE,
thx
