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. | More details on working with Danfoss FC drives are described in document MG.02.A4.02 VLT® Micro Drive FC 51 Operating Instructions.

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. | 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, | In the frequency converter, the frequency values are presented as follows: the frequency 50 Hz (100% of the scale) corresponds to the number 16384.
