Table 3.13 Digital Input Function
FC 300 standard terminals are 18, 19, 27, 29, 32 and 33.
MCB 101 terminals are X30/2, X30/3 and X30/4.
Terminal 29 functions as an output only in FC 302.
Functions dedicated to only one digital input are stated in
the associated parameter.
All digital inputs can be programmed to these functions:
[0] No No reaction to signals transmitted to the
operation terminal.
[1] Reset Resets frequency converter after a TRIP/ALARM.
Not all alarms can be reset.
[2] Coast (Default Digital input 27): Coasting stop,
inverse inverted input (NC). The frequency converter
leaves the motor in free mode. Logic '0' ⇒
coasting stop.
[3] Coast and Reset and coasting stop Inverted input (NC).
reset Leaves motor in free mode and resets
frequency converter. Logic '0' ⇒ coasting stop
inverse
and reset.
[4] Quick stop Inverted input (NC). Generates a stop in
inverse accordance with quick-stop ramp time set in
parameter 3-81 Quick Stop Ramp Time. When
motor stops, the shaft is in free mode. Logic '0'
⇒ Quick-stop.
[5] DC-brake Inverted input for DC braking (NC). Stops
inverse motor by energising it with a DC current for a
certain time period. See parameter 2-01 DC
Brake Current to parameter 2-03 DC Brake Cut In
Speed [RPM]. The function is only active when
the value in parameter 2-02 DC Braking Time is
different from 0. Logic '0' ⇒ DC braking.
[6] Stop Stop Inverted function. Generates a stop
inverse 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,
parameter 3-52 Ramp 2 Ramp Down Time,
parameter 3-62 Ramp 3 Ramp down Time,
parameter 3-72 Ramp 4 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.
Start (Default Digital input 18): Select start for a
start/stop command. Logic '1' = start, logic '0'
= stop.
Latched The motor starts, if a pulse is applied for min.
start 2 ms. The motor stops when Stop inverse is
activated or a reset command (via DI) is given.
(Default Digital input 19). Change the direction
of motor shaft rotation. Select Logic '1' to
reverse. The reversing signal only changes the
direction of rotation. It does not activate the
start function. Select both directions in
parameter 4-10 Motor Speed Direction. The
function is not active in process closed loop.
Used for start/stop and for reversing on the
reversing same wire. Signals on start are not allowed at
the same time.
Disengages the counterclockwise movement
start and allows for the clockwise direction.
forward
Disengages the clockwise movement and
start allows for the counterclockwise direction.
reverse
(Default Digital input 29): Use to activate jog
speed. See parameter 3-11 Jog Speed [Hz].
Shifts between external reference and preset
reference reference. It is assumed that [1] External/preset
on has been selected in parameter 3-04 Reference
Function. Logic '0' = external reference active;
logic '1' = one of the 8 preset references is
active.
Preset ref. bit 0,1, and 2 enables a choice
bit 0 between one of the 8 preset references
according to Table 3.14.
