puma mx2100st spindle warm up alarm

[ssmithprimos]

We began getting a spindle warm up alarm after running most of day. Will run a spindle warm up and still get alarm unable to manually start spindle. Powering down machine and starting back up helps from time to time. any suggestions as to what can cause this?

Check keep relay K13.4 (KNSPW): Milling spindle warming up function is not available (1), or is available (0). This won't fix whatever is causing the issue but it might get you going until you can get it fixed properly. Also, I'd confirm that keep number by checking in your blue book, should be in the pocket in the electrical cabinet door.
