See below.
*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 same limits are applied to Pr 21.02, but based on the value of Pr 21.01.
(If the second motor map is selected Pr 21.01 is used instead of Pr 1.06 and Pr 21.02 instead of Pr 1.07)
The effects of the reference clamps (Pr 1.06 and 1.07), the negative minimum clamp enable (Pr 1.08) and the bipolar reference enable parameters
are defined below.
The variable maximum limit for reference parameters, SPEED_FREQ_MAX, is defined as:
If Pr 1.08 = 0: SPEED_FREQ_MAX = Pr 1.06
If Pr 1.08=1: SPEED_FREQ_MAX is Pr 1.06 or -Pr 1.07 whichever is the largest
(If the second motor map is selected Pr 21.01 is used instead of Pr 1.06 and Pr 21.02 instead of Pr 1.07)
