6.16 Parameter ListsChanges during operation”TRUE” means that the parameter can be changed whilethe frequency converter is in operation. “FALSE” meansthat the frequency converter must be stopped before achange can be made.4-Set-up'All set-ups': the parameter can be set individually in eachof the four set-ups, i. e. one single parameter can havefour different data values.’1 set-up’: data value will be the same in all set-ups.DatatypeDescription Type2 Integer 8 Int83 Integer 16 Int164 Integer 32 Int325 Unsigned 8 Uint86 Unsigned 16 Uint167 Unsigned 32 Uint329 Visible String VisStr33 Normalized value 2 bytes N235 Bit sequence of 16 boolean variables V254 Time difference w/o date TimDTable 6.166.16.1 ConversionThe various attributes of each parameter are displayed inFactory Setting. Parameter values are transferred as wholenumbers only. Conversion factors are therefore used totransfer decimals.4-12 Motor Speed Low Limit [Hz] has a conversion factor of0.1. To preset the minimum frequency to 10 Hz, transferthe value 100. A conversion factor of 0.1 means that thevalue transferred is multiplied by 0.1. The value 100 istherefore read as 10.0.Examples:0s ⇒ conversion index 00.00s ⇒ conversion index -20ms ⇒ conversion index -30.00ms ⇒ conversion index -5Conversion index Conversion factor1007574676 10000005 1000004 100003 10002 1001 100 1-1 0.1-2 0.01-3 0.001-4 0.0001-5 0.00001-6 0.000001-7 0.0000001Table 6.17 Conversion TableParameter Descriptions Operating Instructions VLT® CDS302 and CDS303122 MG34M302 - VLT® is a registered Danfoss trademark/Commercial Compressor66
