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 acti-
vate 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 0 0 1
Preset ref. 2 0 1 0
Preset ref. 3 0 1 1
Preset ref. 4 1 0 0
Preset ref. 5 1 0 1
Preset ref. 6 1 1 0
Preset ref. 7 1 1 1
[19] Freeze ref Freezes actual reference. The frozen reference is now the point of enable/
condition for Speed up and Slow 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/condition for Speed up and Slow 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.
NOTE: When Freeze output is active, the adjustable frequency drive can-
not be stopped via a low ‘start [13]’ signal. Stop the adjustable frequency
