Actual Speed

= Data / 1.6384 * M mm/s or deg/s
= Data / 1.6384 microsteps/s
= Data / 1.6384 / R steps/s
= Data / 1.6384 / (R x S) * 60 revolutions/min Motor rpm
= Data / 1.6384 * L / (R x S) mm/s Linear devices only


  • Data is the value of the command data
  • R (microsteps/step) is the microstep resolution (command 37)
  • S (steps/revolution) is the number of steps per motor revolution
  • M (mm or deg) is the microstep size
  • L (mm or deg) is the distance of linear motion per motor revolution

Refer to product specifications for the distance corresponding to a single microstep or revolution.

For example, if a motor has 200 steps per revolution (S = 200), used with default resolution (R = 64), and Data is 251658, then the motor will move at a speed of 720 revolutions per minute.
