Latched
start
If a pulse is applied for minimum 2 ms, the
motor starts. The motor stops when stop
inverse is activated, or a reset command (via
DI) is given.
[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
parameter 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 counterclockwise movement
and allows clockwise direction.
[13] Enable
start
reverse
Disengages the clockwise movement and
allows counterclockwise direction.
[14] Jog
(Default digital input 29): Activate jog speed.
See
parameter 3-11 Jog Speed [Hz]
.
[15] Preset
reference
on
Shifts between external reference and preset
reference. It is assumed that
[1] External/preset
has been selected in
parameter 3-04 Reference
Function
. Logic 0 = external reference active;
logic 1 = 1 of the 8 preset references is active.
[16] Preset ref

[19] Freeze
ref
Freezes the actual reference, which is now the
point of enable/condition to be used for
[21] Speed
up
and
[22] Speed down
. If speed up/speed down
is used, the speed change always follows ramp 2
(
parameter 3-51 Ramp 2 Ramp Up Time
and
parameter 3-52 Ramp 2 Ramp Down Time
) in the
range 0–
parameter 3-03 Maximum Reference
.
[20] Freeze
output
Freezes the actual motor frequency (Hz), which is
now the point of enable/condition to be used for
[21] Speed up
and
[22] Speed down
. If speed up/
speed down is used, the speed change always
follows ramp 2 (
parameter 3-51 Ramp 2 Ramp Up
Time
and
parameter 3-52 Ramp 2 Ramp Down Time
)
in the range 0–
parameter 1-23 Motor Frequency
.
NOTICE
When freeze output is active, the frequency
converter cannot be stopped via a low
[8]
Start
signal. Stop the frequency converter
via a terminal programmed for
[2] Coasting
inverse
or
[3] Coast and reset inverse
.
[21] Speed
up
Select
[21] Speed up
and
[22] Speed down
for digital
control of the up/down speed (motor potenti-
ometer). Activate this function by selecting either
[19] Freeze ref
or
[20] Freeze output
. When speed
up/speed down is activated for less than 400 ms,
the resulting reference is increased/decreased by
0.1%. If speed up/speed down is activated for
more than 400 ms, the resulting reference follows
the setting in ramping up/down parameters 3-
x1/3-x2.

[26] Precise
stop inv.
Sends an inverted stop signal when the precise
stop function is activated in
parameter 1-83 Precise Stop Function
.
Precise stop inverse function is available for
terminals 18 or 19.
[27] Precise
start, stop
Use when
[0] Precise ramp stop
is selected in
parameter 1-83 Precise Stop Function
.
Precise start, stop is available for terminals 18
and 19.
Precise start ensures that the rotor turning
angle from standing still to reference is the
same for each start (for same ramp time, same
setpoint). This function is the equivalent to the
precise stop where the rotor turning angle from
reference to standing still is the same for each
stop.
When using
parameter 1-83 Precise Stop Function
option
[1] Cnt stop with reset
or
[2] Cnt stop w/o
reset
