Selection number Selection name Selection description
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 .
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 .
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.
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 .
34 Ramp Bit 0 Enable a selection from the 2 ramps available.
45 Latched Start Reverse The motor starts to run reverse when a pulse is applied for
minimum 4 ms. The motor stops when stop commands are
given.
51 External Interlock This function makes it possible to give an external fault to
the frequency converter. This fault is treated as an internally
generated alarm.
60 Counter A (up) Input for increment counting in the SLC counter A.
61 Counter A (down) Input for decrement counting in the SLC counter A.
62 Reset Counter A Input for reset of counter A.
