Volt 4
Set the parameter values, both frequency and voltage for up to four points to create
a custom V/F curve. Frequencies are set to correspond with each voltage. The
defined points are between the start frequency and the base frequenciy.
The 100% output voltage in the figure below is based on the parameter settings of bA.15 (motor
rated voltage). If bA.15 is set to 0 it will be based on the input voltage.
•
When a normal induction motor is in use, care must be taken not to configure the output pattern
away from a linear V/F pattern. Non-linear V/F patterns may cause insufficient motor torque or
motor overheating due to over-excitation.
•
When a user V/F pattern is in use, forward torque boost (dr.16) and reverse torque boost (dr.17) do
not operate.
