No reaction to signals transmitted to terminal.
Resets frequency converter after a TRIP/ALARM. Not all alarms can be reset.
Leaves motor in free mode. Logic '0' => coasting stop.
(Default Digital input 27): Coasting stop, inverted input (NC).
Leaves motor in free mode and resets the frequency converter. Logic '0' => coasting stop and reset.
Inverted input for DC braking (NC).
Stops motor by energizing it with a DC current for a certain time period. See par. 2-01 to par. 2-03. The function
is only active when the value in par. 2-02 is different from 0. Logic '0' => DC braking.
Stop Inverted function. Generates a stop function when the selected terminal goes from logical level '1' to '0'.
The stop is performed according to the selected ramp time (par. 3-42, par. 3-52, par. 3-62, par. 3-72).
