<p>The method involves separating data (26, 28, 30) or whole of data and/or utilizable data bit into relevant parts (36, 28, 40) and small relevant parts (42, 44, 46). The parts are stored with an error-correcting mode by addition of parity bits (34), where ratio of the data bit to a number of parity bits for the former parts is greater than number of utilizable data bit to number of parity bits for the latter parts. A preset number of high order bits is used for the former parts. The data from a control device of a frequency converter is transferred to a power part. Independent claims are also included for the following: (1) a computer program comprising a program code unit with a set of instructions to perform a method for transferring data to a drive unit (2) a computer program product comprising a program code unit with a set of instructions to perform a method for transferring data to a drive unit (3) a digital storage medium comprising electronic readable control signals to perform a method for transferring data to a drive unit (4) a drive unit comprising a control device.</p> |
