ATV12 for local speed control and 3 wire start stop on terminals.

Product Line:

Cause:

Resolution:
First hold the MOD button for 3 seconds to put the drive in local mode.  The LED display will flash LOC.

You are now in local mode at this point and can not do any programming until you put the drive in programming mode by holding the ESC button for 3 seconds until the 3 Leds all blink at once.

Now you can program the drive

Confg menu enter
Full menu enter
CLT menu enter

CHCF= SEP  enter
Cd1= Term enter

ESC back to the CTL menu  now arrow down until you see IO menu and enter
tCC= to 3C or 3 wire control ( note you must hold enter down for 2 seconds before the parameter can be set to 3C)

You must now get the drive back on local mode by hold the ESC button again for 3 seconds until the 3 display LEDs are flashing 1 2 3 again.

you will need to wire the drive as follows
LI1 is NC stop to +24vdc
LI2 is NO Start to +24vdc
The local knob or wheel will be the speed control at this point.
