Menu 21: Second motor parameters

The following parameters are used instead of the normal motor set-up parameters when Pr 11.45 = 1.
When the alternative parameter set is being used by the drive the decimal point second from the right in the 1st row is on.
For more information about a particular parameter, see the equivalent normal motor map 1 parameter.
