connected to the product.
12.1 ANALOG INPUTS
With the analog inputs, it is possible, for instance, to use an external speed reference or to connect a sensor
in order to measure temperature (PTC). Details for those configurations are described in the parameters below.
P0018 – Analog Input Value AI1
P0019 – Analog Input Value AI2
P0020 – Analog Input Value AI3

READ, I/O
Description:
Those read-only parameters indicate the value of the analog inputs AI1, AI2 and AI3 in percentage of the full
scale. The indicated values are those obtained after the offset action and multiplication by the gain. Check the
description of parameters P0230 to P0245.
