Danfoss FC 300

[4] Quick stop inverse Inverted input (NC). Generates a stop in accordance with quick-
stop ramp time set in par. 3-81. When motor stops, the shaft is
in free mode. Logic ‘0’ => Quick-stop.
[5] DC-brake inverse 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.
[6] Stop inverse Stop Inverted function. Generates a stop function when the se-
lected 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).
NB!
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 con-
verter stops, configure a digital output to
Torque
limit & stop
[27] and 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 start The motor starts, if a pulse is applied for min. 2 ms. The motor
stops when Stop inverse is activated.
[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 par. 4-10
Motor Speed Direc-
tion
. The function is not active in process closed loop.
[11] Start reversing Used for start/stop and for reversing on the same wire. Signals
on start are not allowed at the same time.
[12] Enable start forward Rotates motor shaft clockwise at start.
[13] Enable start reverse Rotates motor shaft counterclockwise at start.
[14] Jog (Default Digital input 29): Use to activate jog speed. See par.
3-11.
[15] Preset reference on Shifts 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.
[16] Preset ref bit 0 Preset ref. bit 0,1, and 2 enables a choice between one of the
eight preset references according to the table below.
[17] Preset ref bit 1 Same as Preset ref bit 0 [16].
[18] Preset ref bit 2 Same as Preset ref bit 0 [16].
