Scanning the analog value in on the CIO21A option card

The strain gauge is scanned via the CIO21A option card integrated in the inverter of the top drive (MDA, MDX). The option slot for the CIO21A option card is available as of the following inverter sizes:

• MDA: sizes from 16 A
• MDX: in all sizes

The analog value must be applied at AI 21. In the case of deflection in a positive direction, a negative analog value must be output. In the case of deflection in a negative direction, a positive analog value must be output.
