CV3100 series and MINI series high performance general purpose inverter instruction manual
There are four groups of Accel. & Decel., the others(2,3,4) are defined by P2.22-P2.27,
which factory setting are P0.14、P0.15. If other groups needed, please choose by
control terminals.
P0.16 V/F curve setting
Setting range
0：Constant torque curve
Suitable for normal constant torque loads, of which voltage output is linearity to
frequency output.
1: Decreasing torsion curve 1
Output 1.7 hypo-power decline torsion curves.
2: Decreasing torsion curve 2
Output 2.0 hypo-power decline torsion curves.
Max output
voltage
P0.09
Curve 1 and 2 are suitable for variable loads such as fan, pump and so on. Curve2 is
better in energy saving than Curve 1. However, it will be unstable for the motor being
out of excitation status under running at Curve 1 and 2. The curve choice or setting
must base on specific conditions. Of course,the user can also adopt user-defined V/F
curve.
3：User-defined V/F curve
Requisite V/F curve can be set through P0.17—P0.22, shown as Diagram 6-5.
Note：Only when P0.00=1，this group parameter is available.
