Active JOG increment, i.e. a position increment that is executed with each user jog command. Usually, there are predefined increments given (1/10, 1/100, 1/1000 position increment in the selected physical unit), but a continuous jog mode and a jog mode with variable increment are possible, too. A continuous jog mode is indicated with a jog increment value of -1, all other jog increments are given as real increments in the appropriate units.
