first , give us the type of spindle drive (A06B-6***-H*** ) or the pcb type (A20B-****-****) or (A16B-****-****)

Hi,
I checked the board, and here is what I saw.
AC SPINDLE SERVO UNIT
Type No. A06B-6052-H001
Mfg. No. P7Y000595
On the boards,
(the one in back) A16B-1100-009?/09D
(the one in front) A16B-1100-0080, Edition 08D
Any information on the spindle drive unit is appreciated.
Thanks again,
Bill Gillen
ok, first thing, you have to check sensor signal by an oscilloscope turning spindle by hand . you have check points at the bottom of the pcb, just near CN2 connector .they are called Pa,Pb, Ra, Rb. You must found a sinusoid of about 3.5 volts on the a, and continuous 3 volts on the two others.
Hi,
My alarms sheet, item 2 under "Speed is deviated from the command value" suggests the Transistor module is defective. The Check Procedure says Transistor collector-emitter is open, and the Remedy is Replace Transistor module.
Is there a simple way to test this transistor module? Or is it one of those situations where you "guess, spend the money and go to the next problem"?
I found this transistor module, and wanted to ask; Is this the module they are talking about?
A50L-0001-0209 Fanuc Transistor Module: Darlington.
Also, if it is, I think I know where it goes, but wanted to ask. I think it goes behind the double stacked circuit board near the center of the cabinet. Is that correct?
Thank you again,
Bill Gillen
