6.2.5 5-1* Digital Inputs
Parameters for configuring the input functions for the
input terminals.
The digital inputs are used for selecting various functions
in the frequency converter. All digital inputs can be set to
the following functions:
Options [120] - [138] are related to the cascade controller
functionality. For more information, see parameter group
25-** Cascade Controller.

Table 6.7 Functions for Digital Inputs
All = Terminals 18, 19, 27, 29, 32, X30/2, X30/3, X30/4. X30/
are the terminals on MCB 101.
Functions dedicated to only one digital input are stated in
the associated parameter.
All digital inputs can be programmed to these functions:
[0] No operation No reaction to signals transmitted to
terminal.
[1] Reset Resets frequency converter after a TRIP/
ALARM. Not all alarms can be reset.
[2] Coast inverse Leaves motor in free mode. Logic '0'
⇒coasting stop.
(Default Digital input 27): Coasting stop,
inverted input (NC).
[3] Coast and Reset and coasting stop inverted input (NC).
reset inverse Leaves motor in free mode and resets the
frequency converter. Logic '0'⇒coasting stop
and reset.
[5] DC-brake Inverted input for DC braking (NC).
inverse Stops motor by energising it with a DC
current for a certain time period. See
2-01 DC Brake Current to 2-03 DC Brake Cut
In Speed [RPM]. The function is only active
when the value in 2-02 DC Braking Time is
different from 0. Logic '0' ⇒DC braking.
This selection is not possible when
1-10 Motor Construction is set to [1] PM, non
salient SPM.
[6] Stop inverse 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 (parameter 3-42 Ramp 1 Ramp Down
Time and 3-52 Ramp 2 Ramp Down Time.
NOTICE
When the frequency converter is at
the torque limit and has received a
stop command, it may not stop by
itself. To ensure that the frequency
converter stops, configure a digital
output to [27] Torque limit & stop and
connect this digital output to a digital
input that is configured as coast.
