User Defined Coefficient K
Settings
0. 1 to 160.0
Factory Setting: 1.0
The coefficient K determines the multiplying factor for the user-defined unit.
When Pr00.04 is set to 0:
User-defined unit (U) = Output frequency (H) * User Defined Coefficient (K)
When Pr00.04 is set to 16:
User-defined unit (U) = Output frequency (F) * User Defined Coefficient (K)
Or PID frequency setting * User Defined Coefficient (K)
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.

The function of this parameter is to input the password that is set in Pr.00.09. Input the correct
password here to enable changing parameters. You are limited to a maximum of 3 attempts.
After 3 consecutive failed attempts, a blinking “codE” will show up to force the user to restart
the AC motor drive in order to try again to input the correct password.
