If a signal that does not change in value but is updated/monitored periodically (1 Hz) is input to the SoftMotor's Readback, and -1 is entered in the "$(P)$(SM)CalcRevs.MDEL" field, the motor record is updated at a very fast rate.

The issue was resolved when the above line in softMotor.db was changed from PP to NPP.
Is there a reason to use PP instead of NPP? I'm also curious about why the CPU usage increases significantly when using PP.
