Issue:
How is a damper control circuit set up on an open type ATV312, ATV71, ATV12 drive?

Product Line:
Altivar open type ATV drives

Environment:
All

Cause:
The drive should not run until the damper is open.

Resolution:
The end customer's run signal can control the damper solenoid.  Once the damper is open, a sensor or limit switch can indicate an open damper status.  This damper end switch should give a contact closure to the RUN logic input on the VFD.

Note that the ATV212 and ATV61 have damper control functions integral to the standard product.
