 More details on working with Danfoss FC drives are described in document MG.02.A4.02 VLT® Micro Drive FC 51 Operating Instructions. Below is a table with parameters. The parameter numbers specified in these tables must be specified in the register settings with an offset of -1. For example, the Bus reference register (REF) in the documentation has the address 50000, but in the WebHMI you set it as HR49999.

 To access any paramter you can use the formula: (Pr.Num. * 10 - 1). E.g. 8-31 (bus address) will equal 831*10 - 1 = 8309.

 In the frequency converter, the frequency values are presented as follows: the frequency 50 Hz (100% of the scale) corresponds to the number 16384. Negative values are also a number in binary complementary form (two's complement). Therefore, to correctly display the frequency and its task for the registers, it is necessary to use the multiplier 50/16384 = 0.0030517578125, and specify the appropriate format in the register properties.
