7.4.15. Keypad settings
In the submenu S6.6 under the System menu you can further customise your frequency converter operator interface.
Locate the Keypad settings submenu (S6.6). Under the submenu, there are two pages (P#) associated with the keypad operation, Default page
(P6.6.1) and Timeout time (P6.6.3)
Default page (P6.6.1)
Here you can set the location (page) to which the display automatically moves as the Timeout time (see below) has expired or as the power is
switched on to the keypad.
Press the Menu button right once to enter the edit mode. Pressing the Menu button right once again makes you able to edit the number of the
submenu/page digit by digit. Confirm the new default page value with the Enter button. You can return to the previous step anytime by pushing the
Menu button left.
Note! If you set a page that does not exist in the menu, the display will automatically move to the last available page in the menu.
