A single axis $$CNC$$ table is driven by a $$DC$$ servo motor that is directly coupled to a lead screw of $$5$$ $$mm$$ pitch. The circular encoder attached to the lead screw generates $$1000$$ voltage pulses per revolution of the lead screw. The table moves at a constant speed of $$6$$ $$m/min.$$ The corresponding frequency (in $$kHz$$) of the voltage pulses generated by the circular encoder is __________________.
