SF - Step Filter Frequency
Compatibility: Stepper drives only
Sets or requests the step filter frequency. The primary use of this filter is to introduce “microstep emulation”
effects, which smooth out low resolution step pulses when the drive’s microstep/gearing resolution (EG command)
is set to a low value. This command is exceptionally useful when using a low-resolution indexer and smooth motor
shaft rotation is required.
