Starting and stopping the drive with +24v and LI1 FWD and using the remote keypad's knob as speed control.

Hold the MOD button until you see the 3 LEDs on the left of the local display all flash at once.
This is local mode you can not do any programming in this mode.

Now you are in local/ programming mode. 
Push the enter button or knob. 
Scroll down to CTL menu enter
Scroll down to LAC menu enter
Set LAC to L3 or level 3 (you must hold enter for 3 seconds before the parameter will save) ESC
scroll down to FR1
Set FR1 to A1U1 
Scroll down to CHCF enter
Set CHCF to SEP enter
Scroll down to CD1 enter
Set CD1 to term for terminal control enter
Once you are done programming you will need to put the drive back in Local run mode by holding the ESC button again for 3 seconds until you see the 3 LED's all flash at once.
Now you can start the drive in 2 wire control by closing LI1 to +24vdc and use the remote HMIs knob for speed control.
