Parameters: 3-** Reference/Ramps - Danfoss VLT AutomationDrive FC 301 Programming Manual

Parameter Descriptions
3.3.5 2-3* Adv. Mech Brake
Parameter 2-30 Position P Start Proportional Gain to
parameter 2-33 Speed PID Start Lowpass Filter Time can be
set up for very smooth transition change from speed

control to position control during parameter 2-25 Brake
Release Time - the time when the load is transferred from
the mechanical brake to the frequency converter.
Parameter 2-30 Position P Start Proportional Gain to
parameter 2-33 Speed PID Start Lowpass Filter Time are
activated when parameter 2-28 Gain Boost Factor is set to 0.
See Illustration 3.20 for more information.

Function:
Signal values can be positive only,
or positive and negative. The
minimum limit may have a negative
value, unless [1] Speed closed loop
control or [3] Process is selected in
parameter 1-00 Configuration Mode.
Min - Max Select the range of the reference
signal and the feedback signal.
Signal values can be positive only,
or positive and negative. The
minimum limit may have a negative
value, unless [1] Speed closed loop
control or [3] Process is selected in
parameter 1-00 Configuration Mode.
-Max - +Max For both positive and negative
values (both directions, relative to
parameter 4-10 Motor Speed
Direction).
Function:
Select the unit to be used in
process PID control references and
feedbacks. Parameter 1-00 Configu-
ration Mode must be either [3]
Process or [8] Extended PID Control.
