Digital and Analog Inputs and Outputs
CFW300 | 12-3
12
Description:
These parameters define the analog inputs functions.
When the 0 option is selected (Reference Frequency), the analog inputs can provide the reference for the motor,
subject to the specified limits (P133 and P134) and to the action of the ramps (P100 to P103). However, in order
to do so, it is also necessary to configure parameters P221 and/or P222, by selecting the use of the desired
analog input. For further detail, refer to the description of those parameters in Chapter 7 LOGICAL COMMAND
AND FREQUENCY REFERENCE on page 7-1 .
Option 4 (PTC) configures the input to monitor the motor temperature. For further details on this function, refer
to Section 14.4 OVERCURRENT PROTECTION (F070) on page 14-4 .
Option 7 (PLC Use) 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 SoftPLC user’s manual.
Options 16 and 17 configure the input for the use of the PID Controller application (P903 = 1). For further details,
see
Chapter 18 APPLICATIONS on page 18-1 .
