Hi,

Name is Chuck. we were asked to look at a Cincinnati Sabre 750 CNC.

Here is a brief synopsus of what we have going on.

1) customer reported keyboard not functioning.
Removed monitor and inspected connections (OK). Had 237 user ram initialized alert. After power off then back on again 237 alert went away. Checked connections on main board and I/O board (OK).

2) Checked to see if panel definition parameters were set correctly. Was unable to set REC# 121 to maintained from pulsed. Contacted Cincinnati and found out that memory board has lost the ladder program and parameters for machine. REL 1.2 M2C part # 7-000-5032NA software and board Part # 3-533-0908G Brought in "Replacement Board and installed".

3)Loaded SYSCOM data and MTBCOM data trying to load servo and spindle data but could not.

4) Basically on the LC control now on the input/output there is no 24Volt input.

Any Ideas? Sure would appreciate any help.

Thanks,
Chuck Gerchow
