User V/F pattern Setting Details
BAS-41 User Freq 1–
BAS-48 User Volt 4
Set the parameter values to assign arbitrary frequencies (User Freq 1–4) for start
and maximum frequencies. Voltages can also be set to correspond with each
frequency, and for each user voltage (User Volt 1–4).
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)
