6.1 Find the Parameter List.

This example demonstrates the steps required to set parameter
P401 which is Rated Motor Current.

With the motor stopped, press the “PROG” button to access the
parameter list. The display will show the letter “P” followed by a
three digit number. Typically, this is P000 as shown in the illustration
opposite.

6.2 Find the Parameter to change

Use the up and down keys to find the required parameter. In this
example, P401.

Press the “PROG” key to select the parameter value.

6.3 Set the Parameter Value

Use the up and down keys to set the parameter value as required.
In this example, the motor nameplate shows a rated current of
6.47A so the value is set accordingly.

Note: If you are unable to change the value, ensure that parameter
P000 is set to 5. Some parameters may be read-only so cannot be
changed even when P000 is set to 5.

6.4 Finished.

Press “PROG” to save changes. The display will return to the
current parameter.
