TESTWIN must always be less than par. 33-46
TESTVAL.
Function
TESTWIN indicates the size of the target window. A
position is only viewed as reached when the refe-
rence-run (trapeze) is executed, the actual position
is within the window and the velocity is less than
par. 33-46 Target Window Limit Value (Precondition
I: TESTWIN and TESTTIM are activated.)
In this content the velocity is given as TESTVAL in
qc/TESTTIM.
The controller wait to execute the next command
until the actual position is within the target
window.
If TESTWIN is not active [0], then the target has
been reached if the set position is the target posi-
tion. However, this does not necessarily correspond
with the actual position of the drive.
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 corresponding positioning command.
A target window of [0] deactivates the monitoring
of the actual position and only monitors the com-
mand position.
NB!:
Modified handling of TESTWIN to adapt to
the needs of CANopen: If TESTTIM is set
but TESTVAL is not set, then the CANopen
case is assumed. In that case, it is checked if the
time within the TESTWIN is longer than TESTTIM.
If so, then the position has been reached. Other-
wise, the position has not been reached.
TESTWIN handling is modified starting with version
MCO 5.00.

You can program all digital inputs 1 – 10 (12) to
these functions:
– No function [0]: No reaction on signals from the
input_n.
– Home switch no [1]: Defines digital input_n of
MCO 305 as home switch. Behavior after
reaching see HOME_TYPE.
– Home switch nc [2]: Defines digital input_n as
home switch inverse. Behavior after reaching,
see HOME_TYPE.
– Negative end switch no [3]: Defines digital
input_n as the negative end switch.
– Negative end switch nc [4]: Defines digital
input_n as the negative end switch inverse.
– Positive end switch no [5]: Defines digital
input_n as the positive limit switch.
– Positive end switch nc [6]: Defines digital
input_n as the positive limit switch inverse.
