resulting reference will be increased/ decreased by
0.1 %. If Speed up/ down is activated for more than
400msec. the resulting reference will follow the
setting in ramping up/ down parameter 3-x1/ 3-x2.

[23] Set-up
select bit

Select Set-up select bit 0 or Select Set-up select
bit 1 to select one of the four set-ups. Set
0-10 Active Set-up to Multi Set-up.
[24] Set-up

(Default Digital input 32): Same as Set-up select
bit 0 [23].
[26] Precise
stop inv.
Sends an inverted stop signal when the precise
stop function is activated in
1-83 Precise Stop
Function .
Precise stop inverse function is available for
terminals 18 or 19.
[27] Precise
start, stop
Use when Precise ramp stop [0] is selected in
1-83 Precise Stop Function .
Precise start, stop is available for terminals 18 and
19.
Precise start makes sure that the angle that the
rotor turns from standing still to reference is the
same for each start (for same ramp time, same
set-point). This is the equivalent to the precise
stop where the angle that the rotor turns from
reference to standing still is the same for each
stop.
When using for
1-83 Precise Stop Function [1] or
[2]:
The frequency converter needs a Precise Stop
signal before the value of
1-84 Precise Stop
Counter Value is reached. If this is not supplied,
the frequency converter will not stop when the
value in
1-84 Precise Stop Counter Value is reached.
Precise start, stop must be triggered by a Digital
Input and is available for terminals 18 and 19.
[28] Catch up Increases reference value by percentage (relative)
set in
3-12 Catch up/slow Down Value .
[29] Slow
down
Reduces reference value by percentage (relative)
set in
3-12 Catch up/slow Down Value .
[30] Counter
input
Precise stop function in 1-83 Precise Stop Function
acts as Counter stop or speed compensated
counter stop with or without reset. The counter
value must be set in
1-84 Precise Stop Counter
Value .
[31] Pulse
edge
triggered
Edge triggered pulse input counts number of
pulse flanks per sample time. This gives a higher
resolution at high frequencies, but is not as
precise at lower frequencies. Use this pulse
principle for encoders with very low resolution
(e.g. 30 ppr).

[32] Pulse time
based
Time based pulse input measures the duration
between flanks. This gives a higher resolution at
lower frequencies, but is not as precise at higher
frequencies. This principle has a cut-off frequency
which makes it unsuited for encoders with very
low resolutions (e.g. 30 ppr) at low speeds.

available, according to the table below.

[40] Latched
Precise Start
A latched Precise Start only requires a pulse of
3ms on T18 or T19.
When using for 1-83 [1] or [2]:
When the reference is reached, the frequency
converter will internally enable the Precise
Stop signal. This means that the frequency
converter will do the Precise Stop when the
counter value of
1-84 Precise Stop Counter
Value is reached.
[41] Latched
Precise Stop
inverse
Sends a latched stop signal when the precise
stop function is activated in
1-83 Precise Stop
Function . The Latched Precise stop inverse
function is available for terminals 18 or 19.
[51] External
interlock
This function makes it possible to give an
external fault to the drive. This fault is treated
in the same way as an internally generated
alarm.
