How to programme the freque...
[7] External Same function as Coasting stop, inverse, but
Interlock External Interlock generates the alarm
message external fault in the display when
the terminal which is programmed for Coast
Inverse is logic '0'. The alarm message is
also 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
22-00 External Interlock Delay. After applying
a signal to the input, the reaction described
above is delayed with the time set in
22-00 External Interlock Delay.
[8] Start Select start value for a start/stop command.
'1'=start, '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
4-10 Motor Speed Direction.
(Default Digital input 19).
[11] Start Used for start/stop and for reversing on the
reversing same wire. Signals on start are not allowed
at the same time.
[14] Jog Used for activating jog speed. See 3-11 Jog
Speed [Hz].
(Default Digital input 29)
[15] Preset Used for shifting between external reference
reference on 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' = one
of the 8 preset references is active.
[16] Preset ref bit Enables a selection of one of the 8 preset
0 references according to Table 6.8.
[17] Preset ref bit Enables a selection of one of the 8 preset
1 references according to Table 6.8.
[18] Preset ref bit Enables a selection of one of the 8 preset
2 references according to Table 6.8.

Freezes actual reference. The frozen
reference is now the point of enable/
condition for speed up and speed down to
be used. If speed up/down is used, the
speed change always follows ramp 2
(3-51 Ramp 2 Ramp Up Time and 3-52 Ramp
2 Ramp Down Time) in the range 0 -
3-03 Maximum Reference Maximum

the speed change always follows ramp 2

NOTICE
When [20] Freeze output is active, the
frequency converter cannot be
stopped via a low 'start [13]' signal.
Stop the frequency converter via a
terminal programmed for [2] Coast
inverse or [3] Coast and reset, inverse.
For digital control of the up/down speed
(motor potentiometer). Activate this
function by selecting either [19] Freeze
reference or [20] Freeze output. When [21]
Speed up is activated for less than 400 ms
the resulting reference is increased by 0.1%.
If [21] Speed up is activated for more than
400 ms, the resulting reference ramps
according to Ramp 1 in
parameter 3-41 Ramp 1 Ramp Up Time.
Same as [21] Speed up.
Selects one of the 4 set-ups. Set 0-10 Active
Set-up to Multi Set-up.
Same as [23] Set-up select bit 0.
(Default Digital input 32)
Select [32] Pulse input when using a pulse
sequence as either reference or feedback.
Scaling is done in parameter group 5-5*
