Identifier = 1536 + node address = 1536 + 2 = 1538 = 0x0602
(1536 = basic identifier of SDO1 to the controller)
Command = 0x23 = "write request" (request to write a parameter to the controller)
Index = 24575 - code number = 24575 - 88 = 24487 = 0x5FA7
Subindex = 0 (code C00088 has no subcodes)
Data 1 ... 4 = 10.2 x 10 = 102 = 0x00030066
(value for motor current; data type U32; display factor 1/10)
