Hi Johann,

Would you share the Fanuc connector pinout?

Dan

I'll post the info tomorrow.

Looks to be running great :)

What are the rapids on it, looks quite fast.

Dan,

Fanuc type is A06B-6055-H103 with a A20B-1001-0120 orient board.

Connections of CN1 are,

1,2 Speed achieved
3,4 Zero speed
7,8 Ready
11,12 Alarm
22,23 Orient achieved
25,26 Orient
31,32 Analog speed 31=0V 32=0-10V
14,45,46 Spindle start and direction 14=common, 45=FWD, 46=REV
47,48 E-Stop

Hood,

Rapids are set to 275IPM now. Accel needs some further adjustment still.

Thanks  a lot Johann!

Why are the output pins in pairs? Are they relays or what?

Looked faster than that but thats still a very reasonable rapid :)
Are you set up in imperial units?

They are contacts. With the BP the signals run from 24v. The inputs are NO or NC over a relay.

I'm using metric. The speed isn't bad and OK for now although, from the info I can find, the BP412 specs show much higher speeds.

So how do you use the Orient pins, for example, do you have to short pins 25 and 26 to command Orient to the VFD?

And what happens, for example, when speed is achieved? Does an internal relay closes pins 1 and 2?

Yes when you connect 25 and 26 the spindle will position itself and when the position is reached the orient achieved pins 22 and 23 are closed. when you open 25-26 the orient procedure is stopped and 22-23 will open again. While 25-26 is closed the motor is powered and keeps the spindle locked in position.

This weekends effort,

Machined and sand(glass)blasted the operator panel,



Hope to receive the buttons this week.

Yes I think likely 10 to 12m/min would be normal rapid for the BP, maybe even more.

Panel looks great, blasting has given it an excellent look, may have to invest/make  one as that is impressive :)
