7 Drive Machine Data (SIMODRIVE Drive MD) 10.94
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
shift factor . The maximum gain which can be obtained
in this way is 32768 (only the last bit is evaluated).
Offset DAC1 80
Default value Lower input limit Upper input limit Units
0000 FF80 007F Hex

at once
Note:
This machine data is not included in the machine data lists. The DACs are configured in the
course of the drive servo start-up procedure for diagnostic purposes.
Input of an offset value for DAC1 which is added to the value prior to analog output.
Power section code number 95
Default value Lower input limit Upper input limit Units

Note:
This machine data is not included in the machine data lists. During start-up in machine data
dialog, the machine data is set or altered as appropriate via the configuration setting.
Input of code number for the power section used.
