LCD Keypad cannot access drives (PAR) parameter group

LCD Keypad cannot access drives (PAR) parameter group

If a user is having issues locating the (PAR) Parameter Group thru the LCD drive keypad, the following procedure should be performed by selecting keypads MODE button on keypad.  The below assumes the VFD is setup to list only changed parameters. For password lock issues, see our other KB article. 

PROCEDURE:
  1. Press the MODE key. Verify in the upper hand side of LCD screen shows "CNF" . When pressing again you may see "CHG" Changed Parameters but cannot display "PAR" - Parameter/ Programming Mode, no matter how many times the user hits the MODE button. 
  2. MODE key to select the "CNF" - Configuration Mode, then using up/down arrows to select parameter CNF-41, hit PROG/ENTER Key once and change from "View changed" to "View all"  . Press PROG/ENT to save.
  3. Depress the "ESC"  key to go back to the main menu.  Now the user should be able to hit the MODE Key and sequence to the "PAR", along with "CNF" should be available.  
This procedure can also be used in reverse by setting CN41=View changed. This is best used when seeing how a VFD is currently setup.
