Selection number Selection name Selection description
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 or [1] Set-up select bit 1 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.
28 Catch Up Increase reference value by percentage (relative) set in P 5.5.3.13
Freeze Up/Down Step Delta . See Table 66 .
29 Slow Down Reduce reference value by percentage (relative) set in P 5.5.3.13
Freeze Up/Down Step Delta . See Table 66 .
32 Pulse Input The motor starts to run reverse when a pulse is applied for
minimum 4 ms. The motor stops when stop commands are
given.
34 Ramp bit 0 This function makes it possible to give an external fault to
the frequency converter. This fault is treated as an internally
generated alarm.
