Page 17: Information About Positions Tolerance And Hysteresis (Par. U And Y)
Standard user guide Information about positions tolerance and hysteresis (PAR. U and Y) (Not available in program no. 0) The purpose with parameter U is to tell the inverter how accurate the positioning should be. If the ramps (acceleration /deceleration) were set too high would it result in problems with finding the right position precisely. -
