Hello machinists
Can Anyone of you wonderful people possibley help with my annoying little problem ?
I have a Cincinnati milacron arrow 750 milling machine.When i turn on the isolator switch after the machine has been powered down for a couple of days,i get this message on the boot up screens :-
FNC-5
C50000 REV 2.56 (prom)
FNC EXECUTIVE - STANDARD VERSION
CONTROL TECHNIQUES PRECISION SYSTEMS

INITIALISING CNC
CONFIGURED 1/0 MODULES:
MODULE: 0 BUSS ADDRESS:0x0000 ID:4 *** FAIL***
CONFIGURED SERVO MODULES :
MODULE : BUSS ADDRESS : 0x0400 NOT RESPONDING*** FAIL ***
If i manage to get past this to my re-homing the machine screen,the table starts to try and home its self when i have pressed the green power button on the control.Also,just to keep me on my toe's the spindle will rapid down to its hard limit at an eye popping rate past the GOO rapid speed.
Can anyone tell me whats going on ,and why,or what i can ,or should do about this.
Any help or advice would be brilliant,thank you one and all.

I had the same problem.The fault was in the servo module.
