Value Range 0 - Danfoss VLT 5000 Series Manual

8 TESTWIN
TESTWIN indicates the size of the target window. A
position is only viewed as reached when the diffe-
rence between the target and the actual position is
less than the window. The controller wait to execu-
te the next command until the actual position is
within the target window.
If TESTWIN is not active (parameter 0), then the
target has been reached if the set position is the
target position. However, this does not necessarily
correspond with the actual position of the drive.

TESTWIN must always be less than TESTVAL.
NB!
If the target window surrounding the end
position is selected to be too small, the
drive could move in a very small area around the
end position without reaching the target window.
Thus the program would be 'stuck' after the cor-
responding positioning command.
A target window of 0 deactivates the monitoring of
the actual position and only monitors the com-
mand position.

9 VELMAXQC
VELMAXQC determines the Maximum velocity
statements made with the assistance of VELRES
(22) refer to this speed. The sample time is 1 ms.
VELMAXQC is an internal parameter which cannot
be changed. It is automatically calculated from
VELMAX (1) which the user enters in Rpm. These
internal values are decisive for the permitted value
range. However, in practice these limit values are
of no importance since they exceed the encoder
input frequency determined by the hardware by
far.
