00.05 User Defined Coefficient K Unit: 0. 1
Settings 0. 1 to d 160.0 Factory Setting: 1.0
The coefficient K determines the multiplying factor for the user-defined unit.
The display value is calculated as follows:
U (User-defined unit) = Actual output frequency * K (Pr.00.05)
Example:
If user wants to use RPM to display the motor speed when 4-polse motor runs at 60Hz. The
user can display the motor speed by setting Pr.00.04 to 0. The application is shown as follows.
From the formula of motor speed, user-defined unit (U) (RPM) = 60X120/4=1800 (disregard
slip). Therefore, User Defined Coefficient K is 30.0.
