I have a vertical machining center having Fanuc O-MC cnc system. It's spindle motor being stopped in automatic mode while it's feed is not getting hold.
It's spindle drive # A20B-1003-0020 displays shows Alarm No.= 11
I donot have it's manual not even it's alarm discription. ( Alarm 11 ?)
Spindle motor encoder is directly mounted on spindle drive shaft. spindle motor to spindle 1:2 ratio. ( Belt driven ) & orientation card is mounted on spindle drive. Could you also tell me the parameter no. for orientation position (Angle).
kindly help me & send me it's detailed manual.

I believe alarm 11 is "No feedrate commanded". You can probably email the company to get the manuals you need.

Alarm No. 11 is being appeared on the spindle drive seven segment display, spindle gets stop & feed is moving.

Somebody help me as Alarm No. 11 is being appeared on the spindle drive seven segment display, spindle gets stop but feed is moving.
ALARM No. 11?
