7 Drive Machine Data (SIMODRIVE Drive MD)
7.1.2 MSD MD (data description - SW 3)
Input of shift factor DAC1 for analog output. The top 8 bits from a 16-bit wide memory location
are output. This machine data specifies how often the value must be shifted to the left
beforehand. A shift by one position corresponds to a multiplication by 2, i.e. the shift factor
allows multiplication by the power of two 2
in this way is 32768 (only the last bit is evaluated).
