HP/FP board problem (1FP-72)

[robotukas]

Dear robot-forum members,

We have C20G-A robot controller. This controller, unlike other C type controllers has 1FP instead of 1HP. Does anyone have information about this board, input-output terminal deep-switch configuration etc?

When we power on controller LD4 in 1FP-72 board glows red, but no errors apear on multifunction panel.


And when we are trying to power on motors this happens:

Also LD4 (in 1FP-72) starts blinking in the same frequency as motor power switch lamp and motor power doesn't activate.

Any ideas?
