 Main Speed Source_M 1 (Term.[Ai1]) 9 (Option-1)

(BOM Example: image-1640187980182.png)image-1640187974688.png

 
  • CA-03: 31 (Sets S3 input to fast stop)
  • CA-23: 1 (Sets S3 input to Normally Closed)
  • AC-126: 4 (Or to your deceleration time)

You can also modify the fan settings with this parameter.

The RapidPath plugin controls (writes to) some parameters for operation. If you change the value of any of them, your change will be overwritten.

This can be done automatically via Mach.

Go to Configure | Plugins | RapidPath - MachMotion:
