Minarik DIGI-LOK DLC300, User Manual, Page: 9 / 44

As an example, consider an application in which the feedback
source is monitoring a driven shaft, and not the motor armature
shaft. This shaft is to be run at speeds as low as 1 rpm. The
feedback device that you select must produce at least 600 pulses
per revolution.
Conversely, if the application were one that required monitoring
and controlling a driven shaft at speeds as high as 4000 rpm, the
feedback device would be limited to one that produced 30 or
fewer pulses per revolution.
The Digi-Lok® Converter system can control armature shaft
speeds within a 30:1 range. Under no circumstances can the DLC
be expected to control motor speed beyond the speed rating of the
motor.
