(Default Digital input 19).
Used for start/stop and for reversing on the same wire. Signals on start
are not allowed at the same time.
Used for activating jog speed. See par.3-11

Function. Logic '0' = external reference active; logic '1' = one of the eight
preset references is active.

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

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.

WARNING
When Freeze output is active, the adjustable frequency drive cannot be stop-
ped via a low 'start [13]' signal. Stop the adjustable frequency drive via a
terminal programmed for Coasting inverse [2] or Coast and reset, inverse [3].
For digital control of the up/down speed is desired (motor potentiome-
ter). Activate this function by selecting either Freeze reference or Freeze
output. When Speed up is activated for less than 400 msec., the resulting
reference will be increased by 0.1%. If Speed up is activated for more
than 400 msec., the resulting reference will ramp according to Ramp 1
in par.3-41 Ramp 1 Ramp-up
Same as Speed up [21].
