If there is no setting of inflection point in the 3rd
requirement,means to change the requirement as 0.5V
input signal corresponds to 50Hz reference frequency,
and 10V input signal corresponds to 5Hz reference
frequency.Then we can set the inflection point 1 the
same as Min. reference(A3.17
＝
A3.19
，
A3.18
＝
A3.20)
and inflection point 2 the same as Max. reference(A3.13

A3.14

．
If user set the reference of inflection point 2 of curve
4the same as Max. reference(A3.15=A3.13),then the
drive will force A3.16=A3.14,means the setting of
inflection point 2 is invalid.If reference of inflection
point 2 is the same as reference of inflection point
1(A3.17
＝
A3.15),then the drive will force
A3.18=A3.16,means the setting of inflection point is
invalid.If reference of inflection point 1 is the same as
Min. reference(A3.19
＝
A3.17),then the drive will force
A3.20=A3.18,means the setting of Min. reference is
invalid.The setting of curve 1 is in the same manner.
