Table 3.7
[19] Freeze
ref
Freezes the actual reference, which 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 (E-10 Accel
Time 2 and E-11 Decel Time 2) in the range 0 -
F-53 Maximum Reference.
[20] Freeze
output
Freezes the actual motor frequency (Hz), which 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
(E-10 Accel Time 2 and E-11 Decel Time 2) in the
range 0 - F-04 Base Frequency.
NOTE
When Freeze output is active, the frequency
converter cannot be stopped via a low ‘start
[8]’ signal. Stop the frequency converter via a
terminal programmed for Coasting inverse [2]
or Coast and reset, inverse.
[21] Speed
up
Select Speed up and Speed down if digital control
of the up/down speed is desired (motor potenti-
ometer). Activate this function by selecting either
Freeze reference or Freeze output. When Speed
up/ down is activated for less than 400 msec. the
resulting reference will be increased/ decreased by
0.1 %. If Speed up/ down is activated for more
than 400 msec. the resulting reference will follow
the setting in accel/decel parameters.

[22] Speed down Same as Speed up [21].
[23] Set-up select
bit 0
Select Set-up select bit 0 or Select Set-up
select bit 1 to select one of the four set-ups.
Set K-10 Active Set-up to Multi Set-up.
[24] Set-up select
bit 1
Same as Set-up select bit 0 [23].
[26] Precise stop
inv.
Prolongs stop signal to give a precise stop
independent of speed.
Sends an inverted stop signal when the
precise stop function is activated in
H-83 Precise Stop Function.
Precise stop inverse function is available for
terminals 18 or 19.
[27] Precise start,
stop
Use when Precise ramp stop [0] is selected in
H-83 Precise Stop Function.

[28] Catch up Increases reference value by percentage
(relative) set in F-62 Catch up/slow Down
Value.
[29] Slow down Reduces reference value by percentage
(relative) set in F-62 Catch up/slow Down
Value.
[30] Counter
input
Precise stop function in H-83 Precise Stop
Function acts as Counter stop or speed
compensated counter stop with or without
reset. The counter value must be set in
H-84 Precise Stop Counter Value.
[32] Pulse input Use pulse sequence as either reference or
feedback. Scaling is done in parameter group
group E-6#.
[34] Ramp bit 0 Enables a choice between one of the 4 ramps
available, according to the table below.
[35] Ramp bit 1 Same as Ramp bit 0.
Preset ramp bit 1 0

Ramp 2 0 1
Ramp 3 1 0
Ramp 4 1 1
