[3] Coast and reset inverse Reset and coasting stop Inverted input (NC).
Leaves motor in free mode and resets the adjustable frequency drive. Logic ‘0’ => coasting stop
and reset.
[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, par. 3-72).
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.
[7] External Interlock Same function as Coasting stop, inverse, but External Interlock generates the alarm message ’ex-
ternal fault’ on the display when the terminal which is programmed for Coast Inverse is logic ‘0’.
The alarm message will also be active via digital outputs and relay outputs, if programmed for
External Interlock. The alarm can be reset using a digital input or the [RESET] key if the cause for
the External Interlock has been removed. A delay can be programmed in par.22-00
External Inter-
lock Delay
, External Interlock Time. After applying a signal to the input, the reaction described above
will be delayed with the time set in par.22-00
External Interlock Delay
.
[8] Start Select start for a start/stop command. Logic ‘1’ = start, logic ‘0’ = stop.
(Default Digital input 18)
[9] Latched start Motor starts, if a pulse is applied for min. 2 ms. Motor stops when Stop inverse is activated
[10] Reversing Changes 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
.
(Default Digital input 19).
[11] Start reversing Used for start/stop and for reversing on the same wire. Signals on start are not allowed at the same
time.
[14] Jog Used for activating jog speed. See par.3-11
Jog Speed [Hz]
.
(Default Digital input 29)
[15] Preset reference on Used for shifting 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 Enables a choice between one of the eight preset references according to the table below.
[17] Preset ref bit 1 Enables a choice between one of the eight preset references according to the table below.
[18] Preset ref bit 2 Enables a choice between one of the eight preset references according to the table below.
Preset ref. bit
2 1 0
Preset ref. 0 0 0 0
Preset ref. 1 001
Preset ref. 2 0 1 0
Preset ref. 3 011
Preset ref. 4 1 0 0
Preset ref. 5 101
Preset ref. 6 1 1 0
Preset ref. 7 111
