I/O
the description of those parameters in Chapter 7 COMMAND AND REFERENCES on page 7-1.
Option 4 (PTC) configures the input to monitor the motor temperature. For further details on this function, refer to
Section 10.3 PROTECTIONS on page 10-3.
Option 7 (PLC Use), as well as options 8 to 15, configures the input to be used by the programming done in the
memory area reserved for the SoftPLC function. For further details, refer to the help menu of the WPS software.
Options 16 and 17 configure the input for the use of the PID Controller application (P903 = 1). For further details,
see Chapter 14 APPLICATIONS on page 14-1.
P232 - AI1 Input Gain
P237 - AI2 Input Gain
Range: 0.000 to 9.999
Description:
The parameters define the gains of the analog inputs.
Each analog input of the inverter is defined by the steps of calculation of Signal, Offset, Gain, Filter, Function and
Value AIx, as shown in Figure 9.1 on page 9-1.
P233 - AI1 Input Signal
P238 - AI2 Input Signal
Range: 0 = 0 to 10 V / 20 mA
1 = 4 to 20 mA
2 = 10 V / 20 mA to 0
3 = 20 to 4 mA
Description:
These parameters configure the signal type (if current or voltage) that will be read in each analog input, as well as
its variation range. In options 2 and 3 of the parameters, the reference is inverse, that is, the maximum frequency
is obtained with the minimum reference.
Pay attention to the connections of the analog input with voltage or current signal according to the inverter used.
For analog inputs on expansion accessories, refer to the installation, configuration, and operation guide of the I/O
expansion accessory used.
