### MP-018 MP internal counter error

The low byte of one of the software X/Y/Z counters differs from the low byte of the corresponding hardware counter. This error indicates a probable CPU board failure, not a counter board failure. Refer to MP Error Codes for additional information.

What you should do

1. To clear the error, power the MP down.

2. Power the MP back up.

3. If the error reoccurs, call your Giddings & Lewis service representative.
