Overview
(continued)
The closed-loop control of air-cooled SINAMICS PERFECT
HARMONY GH180 drives is known as NXGpro. This control sys-
tem provides digital and analog input and output functions in the
form of the I/O board and the WAGO I/O modules. 6SR4... drives
use the I/O board, while 6SR3... drives use the I/O board as well
as the WAGO I/O modules.
I/O board
This board has 20 digital inputs, 16 digital outputs, 3 analog
inputs and 2 analog outputs. The main features are shown in the
following table.

WAGO I/O modules
WAGO™ is an off the shelf solution for interfacing digital and
analog I/O to the NXGpro control via the Modbus protocol. The
table below shows some of the WAGO I/O modules that can be
optionally used.
