1. Determining catalog numbers
1. 5. Selecting I/O extension cards (VW3A58201, VW3A58202)
1. 5. 1. ATV38 and I/O option cards (VW3A58201, VW3A58202)
Required information: Connection diagram, presence of an I/O extension card
As standard the ATV 61 has more I/O than the ATV38.
•If the ATV38 is not equipped with an I/O extension card, there is no need to add a card to the Altivar 61. Ignore this section.
• If the ATV38 is equipped with an I/O extension card, it is important to know which inputs/outputs are used as well as thefunction assigned
to AI3 (VW3A58201 card) and to encoder input A, A, B, B (VW3A58201 card).
The tables below can be used to ascertain what was used previously and, therefore, to find the equivalent on ATV 61 with or without an
option card.
