Description:
These parameters define the analog input functions.
When the 0 option is selected (Speed Reference), the analog inputs can provide the reference for the motor,
subject to the specified limits (P0133 and P0134) and to the action of the ramps (P0100 to P0103). However,
in order to do so, it is also necessary to configure parameters P0221 and/or P0222 by selecting the use of
the desired analog input. For further detail, refer to the description of those parameters in
COMMAND AND SPEED REFERENCE on page
Option 3 (SoftPLC) 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.
Option 4 (PTC) configures the input for motor temperature monitoring by means of the reading of a PTC type
sensor, when this sensor is present in the motor. In order to do so, it is also necessary to configure one analog
output (AO) as current source to feed the PTC. More details on this function are presented in
