Use the following procedure to set the motor nameplate values.

Step 1. Click a parameter value and enter a new value to change the value of any of

the displayed parameters.

Step 2. Click Assign to write the motor data values to the drive.

5.3.2 Tuning the Torque/Flux Loop

The torque/flux loop is tuned by using the motor nameplate data, the magnetizing
current value in U.006, and calculating the values for U.014, U. 015, U.019, and U.020
using the torque response, flux response, and overshoot damping values.

When you select Torque/Flux, the Drive Tuning dialog appears with torque/flux loop
data values read from the drive. Figure 5.4 provides an example of the Torque/Flux
Loop dialog box.

ATTENTION: The setting of parameters U.001 (Encoder PPR), U.002
(Motor Poles), U.003 (Motor Nameplate Base Frequency), U.005 (Motor
Nameplate RPM), and U.017 (Motor Top Speed) determines the motor
maximum speed. These parameters must be set by a qualified person
who understands the significance of setting them accurately. Failure to
observe this precaution could result in bodily injury.
