2-60 Digital Inputs
The table below defines which pairs of input functions are in conflict.
Combinations marked with a “ ” will cause an alarm.
Important:There are combinations of input functions in
Table 2.L that
will produce other digital input configuration alarms. “DigIn
CflctA” alarm will also be produced if “Start” is configured and
“Stop – Clear Faults” is not.
Table 2.L Input function combinations that produce “DigIn CflctA” alarm
“DigIn CflctB” indicates a digital Start input has been configured without a
Stop input or other functions are in conflict. Combinations that conflict are
marked with a “ ” and will cause an alarm.
Table 2.M Input function combinations that produce “DigIn CflctB” alarm
“Digin CflctC” indicates that more than one physical input has been
configured to the same input function, and this kind of multiple
configuration isn’t allowed for that function. Multiple configuration is
allowed for some input functions and not allowed for others.
There is one additional alarm that is related to digital inputs: the “Bipolar
Cflct” alarm occurs when there is a conflict between determining motor
direction using digital inputs on the terminal block and determining it by the
polarity of an analog speed reference signal.
Note that the drive will assert an alarm when the user sets up a illegal
configuration rather than refusing the first parameter value that results in
such a configuration. This is necessary because the user may have to change
several parameters one at a time in order to get to a new desired
configuration, and some of the intermediate configurations may actually be
illegal. Using this scheme, the user or a network device can send parameter
updates in any order when setting up the digital input configuration.
