certain time period. See parameter 2-01 DC
Brake Current to parameter 2-04 DC Brake Cut In
Speed [Hz]. The function is only active when
the value in parameter 2-02 DC Braking Time is
different from 0. Logic 0=>DC braking.
NOTICE
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 converter
stops, configure a digital output to [27]
Torque limit and stop and connect this
digital output to a digital input that is
configured as coast.
Stop inverted function. Generates a stop
function when the selected terminal goes from
logic 1 to logic 0. The stop is performed
according to the selected ramp time
(parameter 3-42 Ramp 1 Ramp Down Time,
parameter 3-52 Ramp 2 Ramp Down Time,
parameter 3-62 Ramp 3 Ramp down Time,
parameter 3-72 Ramp 4 Ramp Down Time).
Select start for a start/stop command. Logic
1=start, logic 0=stop.
The motor starts when a pulse is applied for
minimum 4 ms. The motor stops when stop
commands are given.
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.
Used for start/stop and for reversing on the
same wire. Signals on start are not allowed at
the same time.
Disengages the counterclockwise movement
and allows for the clockwise direction.
Disengages the clockwise movement and
allows for the counterclockwise direction.
Use to activate jog speed. See
parameter 3-11 Jog Speed [Hz].
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.
Preset ref. bits 0, 1, and 2 enable the selection
of 1 of the 8 preset references according to
Table 4.4.
Same as [16] Preset ref bit 0.

Freezes the actual reference, which is now the
point of enable/condition for [21] Speed up and [22]
Speed down to be used. If [21] Speed up or [22]
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.
NOTICE
When [20] Freeze output is active, the
frequency converter cannot be stopped by
setting the signal on [8] Start to low. Stop
the frequency converter via a terminal
programmed for [2] Coasting inverse or [3]
Coast and reset, inverse.
Freezes the actual motor frequency (Hz), which is
now the point of enable/condition for [21] Speed
up and [22] Speed down to be used. If [21] Speed up
or [22] 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.
Select [21] Speed up and [22] Speed down if digital
control of the up/down speed is needed (motor
potentiometer). Activate this function by selecting
either [19] Freeze reference or [20] Freeze output.
When speed up/down is activated for less than 400
ms, the resulting reference is increased/ decreased
by 0.1%. If speed up/down is activated for more
than 400 ms, the resulting reference follows the
setting in ramping up/down parameter 3-51/ 3-52.
