The following parameters must be changed after completing the Standard Parameters table

  • P6.2 Primary Remote Speed Reference = 1
  • Set Drive to I/O control by pressing the LOC/REM button, check the arrow indicator.
  • Drive will start/stop by the I/O Terminal, DI1 (PIN 8) will need to have 24VDC applied. Once started, screen will change from PAR menu to REF menu.
    • Initially, the REF speed will the minimum frequency value (P6.3). If that is zero, then so will the Keypad Reference.
    • At the REF menu change the frequency with the ▲(Up) Arrow and the ▼(Down) Arrow [Might need to press OK button to be able to change value].
    • Use the ►(Right) Arrow to be able to select the digits. Then you can use ◄(Left) Arrow and  ►(Right) Arrow to change digit selection
