[2] Coast inverse (Default Digital input 27): Coasting stop, inverted input (NC). The adjustable frequency drive leaves
the motor in free mode. Logic ‘0’ => coasting stop.
[3] Coast and reset inverse Reset and coasting stop Inverted input (NC). Leaves the motor in free mode and resets the adjust-
able frequency drive. Logic ‘0’ => coasting stop and reset.
[4] Quick stop inverse Inverted input (NC). Generates a stop in accordance with the quick-stop ramp time set in
par. 3-81
Quick Stop Ramp Time
. 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
DC Brake Current
to par. 2-03
DC Brake Cut-in Speed [RPM]
. The function is
only active when the value in par. 2-02
DC Braking Time
is different from 0. Logic ’0’ => DC braking.
[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 (par. 3-42
Ramp 1 Ramp-down
Time
, par. 3-52
Ramp 2 Ramp-down Time
, par. 3-62
Ramp 3 Ramp-down Time
, par. 3-72
Ramp 4
Ramp-down Time
).
NOTE!
When the adjustable frequency drive is at the torque limit and has received a
stop command, it may not stop by itself. To ensure that the adjustable frequency
drive 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 Direction
. 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 Disengages the counter-clockwise movement and allows for the clockwise direction.
[13] Enable start reverse Disengages the clockwise movement and allows for the counter-clockwise direction.
[14] Jog (Default Digital input 29): Use to activate jog speed. See par. 3-11
Jog Speed [Hz]
.
[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
Reference Function
. 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].
Preset ref. bit 2 1 0
Preset ref. 0 0 0 0
Preset ref. 1 0 0 1
Preset ref. 2 0 1 0
Preset ref. 3 0 1 1
Preset ref. 4 1 0 0
Preset ref. 5 1 0 1
Preset ref. 6 1 1 0
Preset ref. 7 1 1 1
