Wiring the VW3 A3 401 option card encoder input when replacing an ATV58F
On the Altivar 58F, encoder signals A A- or B B- had to be reversed in order to avoid the motor rotating in the wrong direction. This anomaly
has been corrected on the Altivar 71 and, therefore, the wiring conforms to the signal order A A- B B-.

ATV 71
The encoder card’s connector does not have a terminal for connecting the cable shielding.
This shielding must, therefore, be connected to the power terminals; use a tag connector or an accessory: D23 FA3.
