*The range shown for Pr 1.07 shows the range used for scaling purposes (i.e. for routing to an analog output etc). Further range restrictions are
applied as given below.
The effects of the reference clamps (Pr 1.06 {SE02, 0.23} and 1.07 {SE01, 0.22}), the negative minimum clamp enable (Pr 1.08) and the bipolar
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})
