4.4 Ensuring Program Security

Parameter values can be password-protected using parameter P.051 (Programming

Disable). When programming is disabled, parameter values can be displayed but

cannot be modified from the keypad unless the correct password is entered in P.051.

Note that disabling program changes by means of P.051 will not prevent parameter

changes being made from the serial port or the network.

Use the following procedure to disable/enable parameter programming. (See section

4.3, Displaying or Changing Parameter Values, if you are unfamiliar with modifying

parameters using the keypad/display.)
Step 1. Select parameter P.051 from the Second Menu General parameters. P.051

will appear on the display.

Step 2. Press the ENTER key to access the parameter. A zero will be displayed.
Step 3. Use the ▲ key to increment the value to 26. This is the password number.
Step 4. Press the ENTER key to save the value. P.051 will be displayed.

Parameter programming is disabled when the PASSWORD LED is on and enabled

when the PASSWORD LED is off.

Step 7. Press the ENTER key to save the changed value.

- OR -

Press the PROGRAM key to exit the parameter without changing the

value.

The parameter number will be displayed

again.

Important: The value will not be written into

memory unless the ENTER key

is pressed.
