[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).
NB!
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
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 In-
terlock 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
[19] Freeze ref 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
(par. 3-51
Ramp 2 Ramp Up Time
and par. 3-52
Ramp 2 Ramp Down Time
) in the range 0 - par.
3-03
Maximum Reference
. (For closed loop see par. 20-14, Maximum Reference/Feedb.).
[20] Freeze output Freezes actual motor frequency (Hz). The frozen motor frequency is now the point of enable/con-
dition for Speed up and Speed down to be used. If Speed up/down is used, the speed change always
follows ramp 2 (par. 3-51
Ramp 2 Ramp Up Time
and par. 3-52
Ramp 2 Ramp Down Time
) in the
range 0 - par.1-23
Motor Frequency
.
NB!
When 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 Coasting inverse [2] or Coast and reset, inverse [3].
