Schneider Electric ATV61 manual Selecting I/O extension cards VW3A58201, VW3A58202, ATV38, Ptc

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 the function 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.

Scenario 1: Replacing an ATV38 with or without a VW3A58201 option card:

g Review of the various instances of use of the AI3 input on the VW3A58201 card:

AI3 assignment
PTC	Use LI6 on ATV 61 control card in PTC mode and adjust SW2 (see page xx)
	Use the TH inputs on the VW3 A3 201 or VW3 A3 202 option cards (see page xx)
Speed reference	Two different options
ATV38		ATV 61
AI3 (0..10 V)		AI1 or AI2 if available
AI3 (+/- 10 V)		AI1
