Function:
In parameters 300-307 Digital inputs it is possible to
choose between the different possible functions related
to the digital inputs (terminals 16-33). The functional
options are given in the table on the previous page.
Description of choice:
No function is selected if the frequency converter is
not to react to signals transmitted to the terminal.
Reset resets the frequency converter after an
alarm; however, not all alarms can be reset (trip
locked) cycling mains power supply. See table in
List of warnings and alarms. Reset will be activated
on the rising edge of the signal.

ALTERNATION)
Coasting stop, inverse is used to force the
frequency converter to "release" the motor immediately.
the output transistors are "turned off" to remove
power to the motor, allowing it to coast to stop.
Logic "0" implements this mode.
Reset and coasting stop, inverse is used for
activating coasting stop at the same time as reset.
Logic "0" implements coasting stop and reset. Reset
will be activated on the falling edge of the signal.
DC braking, inverse is used for stopping the motor
by energizing it with a DC current for a given time, see
parameters 114-116 DC brake. Please note that this
function is only active if the value of parameters 114 DC
