Table 3.15 Digital Input Function
®
VLT AutomationDrive FC 301/FC 302 standard terminals
are 18, 19, 27, 29, 32, and 33. VLT
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 1 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): Coast stop, inverted
inverse input (NC). The frequency converter leaves the
motor in free mode. Logic 0⇒coast stop.
[3] Coast and Reset and coast stop inverted input (NC).

frequency converter. Logic 0⇒coast stop 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
the motor stops, the shaft is in free mode.
Logic 0⇒quick stop.
[5] DC brake Inverted input for DC brake (NC). Stops motor
inverse by energizing 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 brake.
[6] Stop Stop inverted function. Generates a stop
inverse function when the selected terminal goes from
logical level 1 to logical level 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, and
•
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 and stop. Connect this digital
output to a digital input that is
configured as coast.
[8] Start (Default digital input 18): Select start for a
start/stop command. Logic 1 = start,
logic 0 = stop.
[9] Latched If a pulse is applied for minimum 2 ms, the
start motor starts. The motor stops when stop
inverse is activated, or a reset command (via
DI) is given.
[10] Reversing (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.
[11] Start Used for start/stop and for reversing on the
reversing same wire. Signals on start are not allowed at
the same time.
