How is a 0-10Vdc speed reference wired to an ATV312 drive?
Issue:
Wiring of a 0-10Vdc for speed reference on the ATV312
Product Line:
All
Cause:
Programming AI1 for an 0-10vdc speed reference.
Resolution :
Wiring an external 2 wire 0-10Vdc signal from a SCADA or building automation system, connect the positive signal to AI1 and the negative 0V to COM on the drive.
Wiring a external POT to control speed via AI1, connect the center wiper of the POT to AI1 and the other two legs will go to +10 and COM. If the POT operates backwards, swap the +10 and COM wires.
Program the VFD so that the AI1 input is the speed reference.
CtL menu, set Fr1 = AI1 (factory default)
CtL menu, set rFC = Fr1 (factory default)
