Description
BAS-41 User Freq 1 –
BAS-48 User Volt 4
Set the parameter values to assign arbitrary frequencies (User Freq x) for
start and maximum frequencies. Voltages can also be set to correspond
with each frequency, and for each user voltage (User Volt x).
The 100% output voltage in the figure below is based on the parameter settings of BAS-15 (motor
rated voltage). If BAS-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 (DRV-16) and reverse torque boost
(DRV-17) do not operate.
