FC 300 Design Guide
How to Program
All = Terminals 1 8, 19, 27, 29, 32, 33, X30/2,
X30/3, X30/4. X30/ are the terminals on MCB 101.
Terminal 29 is available in FC 302 only.
Functions dedicated to only one digital in put are
stated in the associated parameter.
All digital inputs can be programmed to
these functions:
• No operation [0]: The frequency converter will
not react to signals transmitted to the terminal.
• Reset [1]: Reset the frequency converter after
a TRIP/ALAR M. Not all alarms can be r eset.
• Coast inverse [2] (Default Digital input
27): Coasting stop, inverted input (NC). The
frequency converter leaves the motor in free
mode. Logic ‘0’ => coasting stop.
• Coast and reset inverse [3]: Reset and
coasting stop Inverted input (NC). The
frequency converter leaves the m otor in
free mode and resets the drive. Logic ‘0’
=> coasting stop and reset.
• Quick stop inverse [4]: Inverted input
(NC). Generate a stop in accordance with
the quick-stop ramp time set in par. 3-81.
When the motor stops, the s haft is in free
mode. Logic ‘0’ => Quick-stop.
• DC-brake inverse [5]: Inverted input for DC
braking (NC). Stops the 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 inverse [6]:Stop Inverted function.
Generate a s top function wh en the se lecte d
terminal goes from logical level ‘1’ to ‘0’
.The
stop is performed according to the selected ramp
time (par. 3-42, par. 3-52, p ar. 3-62, par. 3-72).
NOTE
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 digita l output to Torque limit & stop
[27] and connect this digital o
utput to a digital
input that is configure d as coast.
• Start [8] (Default Digital input 18): Select
start for a start/stop comm
and. Logic ‘1’
= start, logic ‘0’ = stop.
• Latched start [9]: The motor starts, if a
pulse is applied for min. 2 ms. The motor
stops when Stop inverse is activated.
• Reversing [10]: (Default Digital input 19).
Change the direction of m o tor shaft rotation.
Select Logic ‘1’ to revers e. The reversing
signal only changes the direction of rotation.
It does not activate the start function. Select
both directions in par. 4-10 Motor S peed
Direction. The function is not active in Speed
closed loop [1] or Torque [2] control in
par. 1-00 Configuration Mode.
• Start reversing [11]: Use for start/stop and
for reversing on the same wire. Signals on
start are not allowed at the same time.
• Enable start forward [12]: Use if the motor
shaft must rotate clockwise at start.
• Enable start reverse [13]: Use if the motor
shaft m ust rotate counter-cloc kwise at start.
• Jog [14] (Default Digital input 29): Use
for shifting between external reference a nd
preset reference. Select External/preset [2]
in par. 2 -14. Logic ‘0 ’ = external references
active; Logic ‘1’ = one of the four references
is active according to the ta ble below.
• Preset reference on [15]: Use for shifting
between external reference and preset
reference. It is assumed that External/preset
[1] has been selected in par. 3-04. Logic ’0’
= external reference active; logic ’1’ = one of
the eight preset references is active.
• Presetrefbit0[16]: P reset ref. bit 0,1, and
2 enables a choice between one of the eight
preset references acc o rding to the table belo
w.
• Preset ref bit 1 [17]:SameasPreset
ref bit 0 [16].
• Presetrefbit2[18]: Presetrefbit2[18]
:
Same as Pr eset ref bit 0 [16].
