5. Control Input / Output5-215-9-7 Machine time constant setting(1) Machine time constant settingThe ASR need acknowledge of machine (load) time constant. This value can be set from either serialcommunication or through the Operation panel (this allows two different settings).One of the three types of inputs can be selected by setting a parameter or with the sequence input.Settinginput pointSetting data ExplanationSerial Machine time constant This is a setting value issued from the host computer byserial transmission.Panel O. Panel machine timeconstant −1This is a setting value issued from the parameter (A10-1).O. Panel machine timeconstant −2This is a setting value issued from the parameter (B15-0).(2) Machine time constant setting and changeover sequenceThe interlock sequence for the machine time constant setting is shown below.M ac h ine tim ec on stan t s e ttin gS e ria l, m ac hine tim ec on stan t s e ttin gO .
