DX-32 Problem

I am running a Bridgeport VMC 1000 Mill controlled by DX-32. When I program a tool change, the spindle turns off like it is supposed to do, but I get a message that says "Spindle not up to speed in time" Then the drives shut off and I have to restart everything. What do I need to do to keep the error message from coming up and shutting everything down??

Did you ever figure this problem out? My machine is doing the exact same thing.

...Backup all MTB param's write them down ASAP before something else fails during troubleshooting anything would be my advice to start> then ...power supply voltages would be the 1st to suspect to do age.

Merry Xmas
