When replacing and ATV66 with a ATV61/71, what are the control wiring considerations?

Published date: 18 February 2019

Issue:
When replacing an Open style ATV66 with a ATV61/71, what are the control wiring considerations?

Product Line:
Altivar 66

Environment:
All releases

Cause:
Replacing drives.

Resolution:
When converting the wiring to the Altivar 61/71 drive, discard the wires on CL1 and CL2 (ATV66) , not used on the ATV61/71.
Also the run permissive and run forward are swapped around, between the ATV66 and ATV61/71.
ATV66:        LI1 = run permissive and LI2 = run forward
ATV61/71:   LI1 = run forward and LI2 = run permissive (nSt)  (run permissive, if used assign freewheel stop nSt (Fun Menu 1.7) to LI2))
Most other terminations will be the same.
