P113: V/F Minimum Voltage; P114: V/F Minimum Frequency; Carrier Frequency - Janson Controls FC100 Series Manual

Chapter 6 Description of parameter setting

P113: V/F minimum voltage

V/F minimum voltage setup is relevant to start torque to a certain extend.
Increasing the value of this parameter properly can increase the torque of
starting, it can also cause over current. Generally, it's not necessary to change
the value of P113.

P114: V/F minimum frequency

V/F minimum frequency determines the initial point of V/F curve, it is the
minimum value in V/F curve.
Please refer to the following table for the specific Default setting of each model:

Unit:1
Carrier frequency decides the switching frequency of internal power module. The
factory setting of inverters with different capacity are different because will affect
motor noise, motor heating and disturbance.
Carrier frequency P115
Therefore, when the environment demands running without noise, you shall
increase the value of P115, the maximum load of inverter will decrease. If motor
is far from inverter, you shall lower the value of P115 so as to lower the leakage
current between wires and wire to ground. When the environment temperature or
motor load is high, you shall lower the value of P115 to reduce the heating of the
inverter. Refer to table in P114 for the factory set of P115.
