Overview
The liquid-cooled ROBICON Perfect Harmony drive has a
common control system namely NXGII. This control system
offers digital and analog input and output capabilities
through the use of the I/O breakout board and the I/O
WAGO modules.
I/O breakout board
This board consists of 20 digital inputs, 16 digital outputs,
3 analog inputs and 2 analog outputs. The following table
shows the main characteristics of the I/O breakout board.
I/O WAGO modules
WAGO
TM
is an off the shelf solution for interfacing digital and
analog I/O to the NXGII controller via Modbus protocol. The
table below shows some of the WAGO modules used in the
WCIII series drive.
1)
Only two out of the three analog inputs can be 0 to 10 V; one analog will always be a 4 to 20 mA.
