implemented the last mapping parameter value will be lost.
8.6.2 CT Single Word protocol
All parameter values for the drive must be written as signed 32-bit data values with data
compression off. If data compression is turned on the size of the mapping will depend
on the size of the source or destination parameter
Decimal point information is inserted automatically when the data value is written to the
NOTE
drive and removed when the data value is read. The number of decimal places of the
target parameter must be known. Writing a value of 1234 to a parameter with two decimal
places will produce a value of 12.34 in the target parameter. Similarly, reading a value of
12.34 will return a 32-bit integer value of 1234.
