21Application Control Connection ExamplesTwo-wire Start/StopIn Auto mode, closing the contact to terminal 18 will make the drive run.In any mode, opening the safety interlock contact to terminal 27 will stopthe drive.Set Parameter 302 to Start.Set Parameter 304 to External Fault.Digital Speed Up/downClosing the switch to terminal 32 will make the drive accelerate. Closingthe switch to terminal 33 will make the drive decelerate.Set Parameter 306 to Speed up.Set Parameter 307 to Speed down.Set Parameter 305 to Freeze reference.Potentiometer ReferenceA manual potentiometer is used as a input reference for the drive.Set Parameter 308, Terminal 53, Analog Input Voltage, to Reference.Set Parameter 309, Terminal 53, Min. Scaling, to 0 V.Set Parameter 310, Terminal 53, Max. Scaling, to 10 V.Run PermissiveAfter receiving a run command,the drive will apply power to thedamper motor and wait until itreceives “permission” via theswitch that is connected toterminal 16.Set Parameter 300 to Run Permissive.Set Parameter 302 to Start.Set Parameter 304 to External Fault.Set Parameter 323 to Start Signal Applied.Two Feedback SignalsThe drive processes twoindependent feedbacksignals during closed loopoperation. It can respond tothe sum, difference,average, minimum ormaximum of these signals.Set Parameter 308 to FEEDBACK.Set Parameter 311 to FEEDBACKSet Parameter 417 for the desired operation.Transmitter ConnectionThe drive’s internal 24VDC power supply isused to power anexternal 4 to 20 mAtransducer.Set Parameter 314, Terminal 60, Analog Input Curent, tocorrespond to the purpose of the 4 to 20 mA signal.Set Parameter 315, Terminal 60, Min. Scaling, to 4 mASet Parameter 316, Terminal 60, Max. Scaling, to 20 mA.Because the commons of the +24 VDC power supply and the inputreference follower have separate circuit commons, it is necessary toconnect a jumper between terminals 39 and 55.
