Recommended way to implement spindle enable conditions?

Hi everyone,I'd like to add some safety conditions for enabling the spindle on my lathe.The spindle should only be allowed to start if all required conditions are met, for example:

• The auxiliary drives are enabled.
• The chuck is clamped (clamping pressure is present).
• (I may add more conditions later.)

My first idea was to simply combine these signals with one or morecomponents and use the result as the spindle enable signal.Something along the lines of:Is this the usual way to implement this in LinuxCNC, or is there a better or more recommended approach?How have you implemented spindle interlocks on your machines?Thanks!
