We have replaced the CPU and are now getting the following errors.
4 ORD1 System of units not allowed
12760 ORD3 X illegal software limit switch
12761 ORD4 Z illegal software limit switch


Are these machine data that are entered by the operator, and if so where can I find the correct values?

Sounds like you have lost your parameters. Let me know what control you have, and the machine serial number. I have 4 HIT-18s, and I will send you the closest set I have.

[drkeith]

That would be great.
HYUNDAI HIT-18S
S/N 6-016
SINUMERIK 840C
SIMODRIVE 611-D
MMC V04.09.54 4-3-98

Sorry, my machines are all Fanuc. I think Hyundai has an main office in Chicago. Siemens phone number is 1-800-879-8079, maybe you are lucky and just need a few parameter settings.
