1. If the frequency converter is already running, the controller must first be
disabled with the 0 key (STOP).
2. Press the “P” key in order to change the parameter settings (P000
appears at the display).
3. Select the desired parameter with the ñ or the ò key.
4. The current parameter value can be displayed by pressing the “P” key.
5. Change the parameter value with the ñ or the ò key, and save to mem-
ory with the “P” key.
6. Press the ò key until P000 appears at the display in order to exit the pa-
