Inputs and outputs 300-365In this parameter group, the functions that relate to theinput and output terminals of the frequency converterare defined.The digital inputs (terminals 16, 17, 18, 19, 27, 29, 32and 33) are programmed in parameters 300-307. Thetable below gives the options for programming the in-puts. The digital inputs require a signal of 0 or 24 V DC.A signal lower than 5 V DC is a logic ‘0’, while a signalhigher than 10 V DC is a logic ‘1’.The terminals for the digital inputs can be connectedto the internal 24 V DC supply, or an external 24 V DCsupply can be connected.The drawings in the next column show one Setup us-ing the internal 24 V DC supply and one Setup usingan external 24 V DC supply.Switch 4, which is located on theDip switch control card, is usedfor separating the common po-tential of the internal 24 V DCsupply fromthe common potential of the external 24 V DC supply.See Electrical installation.Please note that when Switch 4 is in the OFF position,the external 24 V DC supply is galvanically isolatedfrom the frequency converter.Digital inputs Terminal no. 16 17 18 19 27 29 32 33parameter 300 301 302 303 304 305 306 307Value:No function (NO OPERATION) [0] [0] [0] [0] [0] [0] [0]Reset (RESET) [ 1] [1] [1] [1] [1]Coasting stop, inverse (COAST INVERSE) [0]Reset and coasting stop, in-verse(COAST & RESET INVERS) [1]Start (START) [ 1]Reversing (REVERSE) [ 1]Reversing and start (START REVERSE) [2]DC-braking, inverse (DC BRAKE INVERSE) [3] [2]Safety Interlock (SAFETY INTERLOCK) [3]Freeze Reference (FREEZE REFERENCE) [2] [2] [2] [2] [2]Freeze output (FREEZE OUTPUT) [3] [3] [3] [3] [3]Selection of Setup, Isb (SETUP SELECT LSB) [4] [4] [4]Selection of Setup, msb (SETUP SELECT MSB) [4] [5] [4]Preset reference, on (PRESET REF.
