5.1.1 Drive ConfiguratorIt is possible to design a frequency converter according tothe application requirements by using the orderingnumber system.The Series offers standard frequency converters andfrequency converters with integral options by sending atype code string describing the product to the localDanfoss sales office, i.e.:FC-360HK37T4E20H2BXCDXXSXXXXAXBXThe meaning of the characters in the string can be locatedin the pages containing the ordering numbers in thischapter.Use the Internet based Drive Configurator for configuringthe right frequency converter for the right application andgenerate the type code string. The Drive Configuratorautomatically generates an eight-digit sales number to bedelivered to a local sales office.Furthermore, it is possible to establish a project list withseveral products and send it to a Danfoss sales represen-tative.The Drive Configurator can be found on the globalInternet site: www.danfoss.com/drives.5.2 Options and AccessoriesDanfoss offers a wide range of options and accessories forVLT® AutomationDrive FC 360.Description Ordering numbersVLT® Control Panel LCP 21 132B02541VLT® Numeric LCP IP55 panel mounting 132B01022VLT® Blind Cover for FC 360 132B02621Standard Control Cassette 132B0255VLT® Decoupling for frame size J1 132B0258VLT® Decoupling for frame sizes J2 & J3 132B0259VLT® Decoupling for frame sizes J4 & J5 132B0260Table 5.3 Options and Accessories1) Two kinds of packages, 6 pcs or 72 pcs2) 2 pcs in one package5.3 Brake ResistorsIn applications where the motor is used as a brake, energyis generated in the motor and send back into thefrequency converter. If the energy can not be transportedback to the motor it will increase the voltage in theconverter DC-line. In applications with frequent brakingand/or high inertia loads this increase may lead to an overvoltage trip in the converter and finally a shut down. Brakeresistors are used to dissipate the excess energy resultingfrom the regenerative braking. The resistor is selected inrespect to its ohmic value, its power dissipation rate andits physical size. Danfoss offers a wide variety of differentresistors that are specially designed to our frequencyconverters. See 2.9.4 Control with Brake Function for thedimensioning of brake resistors.
