Position control by vector control4.6.3 Position control (Pr. 419, Pr. 428 to Pr. 430) by inverter pulse train inputConditional position pulse train command can be input by pulse train input and sign signal (NP) from the JOGterminal.ParameterNumber419(1) OperationNamePosition command sourceselectionInitial Value428 Command pulse selection 0429 Clear signal selection 10SettingRangeDescriptionTurning on the servo on signal (LX) cancels the output shut-off and the operation ready signal (RDY) turns on after0.1s. Turning on the STF (forward stroke end signal) or STR (forward stroke end signal) runs the motor according tothe commanded pulse. When the forward (reverse) stroke end signal turns off, the motor does not run in thatdirection.02Conditional position control function by contactinput.
