### MP-151 D/A updates were late or missing

On an MP-35, the MP has not sent the DCC board new axis position coordinates in the last 32 milliseconds. The digital/analog (D/A) board failed.

On an SMP-400, the servo D/A's have not been updated for at least 8 milliseconds.

Refer to DCC 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.
