12 DIGITAL AND ANALOG INPUTS AND OUTPUTS

This section presents the parameters to configure the CFW300 inputs and outputs. This configuration depends
on the accessory, as per Table 12.1 on page

NOTE!
CFW300 HMI shows just the parameters related to the resources available in the accessory connected
to the product.

12.1 ANALOG INPUTS

With the analog inputs, it is possible, for instance, to use an external frequency reference or to connect a sensor
in order to measure temperature (PTC). Details for those configurations are described in the parameters below.
P018 - Analog Input Value AI1
P019 - Analog Input Value AI2
Adjustable -100.0 to 100.0 %
Range:
Properties: ro
Description:
Those read-only parameters indicate the value of the analog inputs AI1 and AI2 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 P230 to P245.
P230 - Dead Zone of the Analog Inputs
Adjustable 0 = Inactive
Range: 1 = Active
Properties: cfg
Description:
This parameter acts for the analog inputs (AIx) or for the frequency input (FI) programmed as frequency reference,
and it defines if the dead zone in those inputs is Active (1) or Inactive (0).
If the parameter is configured as Inactive (P230 = 0), the signal in the analog inputs will actuate on the frequency
reference from the minimum point (0 V / 0 mA / 4 mA or 10 V / 20 mA), and it will be directly related to the
minimum frequency set in P133. Check
12-1.
