3.1.4 Positioning Special Function Unit [FX2N-10GM, FX2N-20GM]
*1. Do not exceed the maximum rotation speed of the servo motor or the stepping motor.
*2. The minimum command unit sets the 1, 10,102 or 103 in parameters.
*3. The minimum command unit sets the 1, 10-1,10-2 or 10-3 in parameters.
*4. Up to 100 points (table) can be set for the table operation.
