FC 300 Design GuideHow to Program" Parameters: Digital In/Out" 5-0* Digital I/O Mode5-00 Digital I/O ModeOption:*PNP [0]NPN [1]Function:The digital inputs and programmed digitaloutputs are pre-programmable for operationeither in PNP or NPN systems.PNP systems are pulled down to GND. Actionis on positive going pulses (↑).NPN systems are pulled up to + 24 V (internal in thedrive). Action is on negative going pulse (↓).It is not possible to set the parameter whilethe motor is running.5-01 Terminal 27 ModeOption:*Input [0]Output [1]Function:Selects terminal 27 as either a digital input oroutput. Default setting is the Input function. Youcannot set this parameter while the motor is running.5-02 Terminal 29 ModeOption:*Input [0]Output [1]Function:Selects terminal 29 as either a digital input oroutput. Default setting is the Input function. Youcannot set the parameter while the motor is running." 5-1* Digital InputsParameters for configuring the input functionsfor the input terminals.The digital inputs are used for selecting variousfunctions in the adjustable frequency drive. Alldigital inputs can be set to the following functions:No operation [0]Reset [1]Coast inverse [2]Coast and reset inv.

Notall alarms can be reset.ï Coast inverse [2] (Default Digital input27): Coasting stop, inverted input (NC). Theadjustable frequency drive leaves the motor infree mode. Logic í0í => coasting stop.ï Coast and reset inv. [3]: Reset andcoasting stop Inverted input (NC). Theadjustable frequency drive leaves the motorin free mode and resets the drive. Logicí0í => coasting stop and resetï Quick stop inverse [4]: Inverted input(NC).
