1. Determining catalog numbers
PI feedback or summed reference: Three different options
Tachometer: Totally incompatible. Alternative solution: use an incremental encoder.
Scenario 2: Replacing an ATV38 with or without a VW3A58202 option card:
Examples:
- If only LI5 and LI6 are used on the VW3A58202 card
ª An option card is not needed with the ATV 61 because Li5 and Li6 are features of the standard product.
- If only the incremental encoder inputs are used on the VW3A58202 card
ª Use the VW3 A3 407 encoder card.
