Selection number Selection name Selection description
15 Preset Reference On Shift between external reference and preset reference. It is
assumed that
[1] External/preset has been selected in P 5.5.3.5
Reference Function . Logic 0 = external reference active; logic 1=1
of the 8 preset references is active.
16 Preset Ref. Bit 0 Preset reference bits 0, 1, and 2 enable the selection of 1 of the 8
preset references. See
Table 65 .
17 Preset Ref. Bit 1 Preset reference bits 0, 1, and 2 enable the selection of 1 of the 8
preset references. See
Table 65 .
18 Preset Ref. Bit 2 Preset reference bits 0, 1, and 2 enable the selection of 1 of the 8
preset references. See
Table 65 .
19 Freeze Reference Freeze the actual reference, which is now the point of enable/
condition for
[21] Speed up and [22] Speed down to be used.
If [21] Speed up or [22] Speed down is used, the speed change
always follows ramp 2 ( P 5.5.4.9 Ramp 2 Accel. Time and P
5.5.4.10 Ramp 2 Decel. Time ) in the range 0– P 5.5.3.3 Reference
Maximum .
20 Freeze Output Freeze the actual motor frequency (Hz), which is now the point
of enable/condition for
[21] Speed up and [22] Speed down to
be used. If [21] Speed up or [22] Speed down is used, the speed
change always follows ramp 2 ( P 5.5.4.9 Ramp 2 Accel. Time and
P 5.5.4.10 Ramp 2 Decel. Time ) in the range 0– P 4.2.2.4 Nominal
Frequency .
Note:
When [20] Freeze output is active, the frequency converter
cannot be stopped by setting the signal on [8] Start to low .
Stop the frequency converter via a terminal programmed for [2]
Coasting inverse or [3] Coast and reset, inverse .
21 Speed Up Select [21] Speed up and [22] Speed down if digital control of
the up/down speed is needed (motor potentiometer). Activate
this function by selecting either
[19] Freeze reference or [20]
Freeze output . When speed up/down is activated for less than
400 ms, the resulting reference is increased/decreased by 0.1%. If
speed up/down is activated for more than 400 ms, the resulting
reference follows the setting in ramping up/down
P 5.5.4.9 Ramp
2 Accel. Time / P 5.5.4.10 Ramp 2 Decel. Time . See Table 66 .
22 Speed Down Select [21] Speed up and [22] Speed down if digital control of
the up/down speed is needed (motor potentiometer). Activate
this function by selecting either
[19] Freeze reference or [20]
Freeze output . When speed up/down is activated for less than
400 ms, the resulting reference is increased/decreased by 0.1%. If
speed up/down is activated for more than 400 ms, the resulting
reference follows the setting in ramping up/down
P 5.5.4.9 Ramp
2 Accel. Time / P 5.5.4.10 Ramp 2 Decel. Time . See Table 66 .
23 Set-up Select Bit 0 Select [23] Set-up select bit 0 to select 1 of the 2 set-ups. Set P
6.6.1 Active Set-up to [9] Multi Set-up .
25 Start and Coast Select [25] Start and Coast for a start command or coast stop.
Logic 1=start, logic 0=coast stop.
