6.2 How to Program the Active FilterThe factory settings for the filter part of the Low Harmonic Drive are selected for optimal operation with a minimum ofadditional programming. All CT values, as well as frequency, voltage levels and other values directly linked to the adjustablefrequency drive configuration are pre-set.Do not change any other parameters influencing the filter operation. However, selection of readouts and informationdisplayed on the LCP status lines can be customized.To set up the filter, two steps are necessary:1. Change the nominal voltage in 300-10 Active Filter Nominal Voltage2. Make sure the filter is in auto mode (press [Auto On])Overview of parameter groups for the filter partGroup Title Function0-** Operation/Display Parameters related to the fundamental functions of the filter, function of the LCPbuttons and configuration of the LCP display.5-** Digital In/Out Parameter group for configuring the digital inputs and outputs.8-** Communication and Options Parameter group for configuring communications and options.14-** Special Functions Parameter group for configuring special functions.15-** Unit Information Parameter group containing active filter information such as operating data,hardware configuration and software versions.16-** Data Readouts Parameter group for data readouts, such as current references, voltages, control,alarm, warning and status words.300-** AF Settings Parameter group for setting the active filter. Apart from par. 300-10, Active FilterNominal Voltage, it is not recommended to change the settings of this parametergroup.301-** AF Readouts Parameter group for the filter readouts.Table 6.10 Parameter GroupsA list of all parameters accessible from the filter LCP can be found in the section Parameter Options - Filter. A more detaileddescription of the active filter parameters can be found in chapter 6.4 Parameter Lists - Active Filter.6.2.1 Using the Low Harmonic Drive in NPN ModeThe default setting for parameter 5-00 Digital I/O Mode is PNP mode. If NPN mode is desired, it is necessary to change thewiring in the filter part of the Low Harmonic Drive. Before changing the setting in parameter 5-00 Digital I/O Mode to NPNmode, the wire connected to 24 V (control terminal 12 or 13) must be changed to terminal 20 (ground).Programming Instruction ManualMG37A222 Danfoss A/S © Rev. 2014-02-07 All rights reserved. 776 6
