reference enable parameters are defined below.
The variable maximum limit for reference parameters, MAX_SPEED_REF, is defined as:
If Pr 1.08 = 0: MAX_SPEED_REF = Pr 1.06 { SE02, 0.23 }
If Pr 1.08 =1: MAX_SPEED_REF is Pr 1.06 { SE02, 0.23 } or -Pr 1.07 { SE01, 0.22 } whichever is the largest
(If the second motor map is selected Pr 21.01 is used instead of Pr 1.06 { SE02, 0.23 } and Pr 21.02 instead of Pr 1.07 { SE01, 0.22 })
