Digital and Analog Inputs and Outputs
13 DIGITAL AND ANALOG INPUTS AND OUTPUTS
This section presents the parameters for the configuration of the CFW-11 inputs and outputs, as well as the
parameters for the command of the inverter in the Local or Remote Situations.
13.1 I/O CONFIGURATION [07]
13.1.1 Analog Inputs [38]
Two analog inputs (AI1 and AI2) are available in the CFW11 standard configuration, and two more can be
added with the accessories (AI3 and AI4). AI4 is available at the IOA-01 or IOB-01 modules; The input AI3
is only available at the IOB-01 module.
NOTE!
The parameters associated with the AI3 and AI4 analog inputs will be showed on the HMI only
when the IOA-01 or IOB-01 module is connected into the slot 1 (XC41).
With those inputs it is possible, for instance, the use of an external speed reference or the connection of a
sensor for the temperature measurement (PTC). The details for those configurations are described in the
following parameters.
P0018 – AI1 Value
P0019 – AI2 Value

Description:
These read only parameters indicate the value of the analog inputs AI1 to AI4, as a percentage of the full scale.
The indicated values are the ones obtained after the offset action and the multiplication by the gain. Refer to the
description of the parameters P0230 to P0250.
