Description
bA.41
User Freq 1 ~
bA.48
User Volt 4
Select arbitrary frequencies between the start and the maximum
frequencies to set the user frequency (User Freq x). Set the voltage to
correspond to each user frequency with user voltage (User Volt x).
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.
• With a user V/F pattern is in use, forward torque boost (dr.16) and reverse torque boost (dr.17) do
not operate.
