Danfoss VLT AutomationDrive FC 360 Programming Guide

Option Name 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 (parameter 3-51
Ramp 2 Ramp Up Time and parameter
3-52 Ramp 2 Ramp Down Time) in the
range 0–parameter 1-23 Motor Frequency.
 NOTICE
When [20] Freeze output is active,
the drive cannot be stopped by
setting the signal on [8] Start to
low. Stop the drive 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/speed down is activated
for less than 400 ms, the resulting
reference is increased/decreased by 0.1%.
If speed up/speed down is activated for
more than 400 ms, the resulting reference
follows the setting in parameter 3-51
Ramp 2 Ramp Up Time/parameter 3-52
Ramp 2 Ramp Down Time. See Table 16.
[22] Speed down Same as [21] Speed up.
[23] Set-up select bit 0 Select [23] Set-up select bit 0 to select 1
of the 2 setups. Set parameter 0-10 Active
Set-up to [9] Multi Set-up.
[28] Catch up Increase reference value by percentage
(relative) set in parameter 3-12 Catch Up/
Slow Down Value.
[29] Slow down Reduce reference value by percentage
(relative) set in parameter 3-12 Catch Up/
Slow Down Value.
[34] Ramp bit 0 Enable a selection from the 4 ramps
available, according to Table 17.
[35] Ramp bit 1 Same as [34] Ramp bit 0.
