33-41 Negative Software End Limit
Range:
Function:
–500000
[–1073741823
Indicates the negative position limit
*
to +1073741823
for all movements. If this value is
qc]
exceeded, then error 5 is triggered.
This parameter is only active if
parameter 33-43 Negative Software
End Limit Active has been set.
If a positioning command is
entered, which exceeds the limits
set, then it is not executed.
33-42 Positive Software End Limit
Range:
Function:
500000
[–1073741823
Indicates the positive position limit
*
to +1073741823
for all movements. If this value is
qc]
exceeded, then error 4 is triggered.
This parameter is only active if
parameter 33-44 Positive Software
End Limit Active has been set.
If a positioning command is entered,
which exceeds the limits set, it is not
executed.
33-43 Negative Software End Limit Active
Option:
Function:
[0]
Inactive Negative software end limit is not monitored.
*
[1]
Active
The negative software end limit is monitored.
During every movement, checks ascertain whether
the target position is located outside of the
permissible movement range. In this case, error
message 5 is issued in parameter 19-93 Error
Status, and the motor control is switched off.
33-44 Positive Software End Limit Active
Option:
Function:
[0]
Inactive Positive software end limit is not monitored.
*
[1]
Active
The positive software end limit is monitored.
During every movement, checks ascertain whether
the target position is located outside of the
permissible movement range. In this case, error
message 4 is issued in parameter 19-93 Error
Status, and the motor control is switched off.
33-45 Time in Target Window
Range:
Function:
0
[0–10
Once the target window has been reached, the
*
ms]
position is read twice and the difference is
compared with parameter 33-46 Target Window
Limit Value. If the result is lower, then the position
has been reached, otherwise a new reading is
taken. This parameter indicates the time interval
between the measurements.

Operating Instructions
NOTICE
The time is limited to 10 ms because during that time
the application program is blocked, and the monitoring
of the limit switch and the position error is not active.
33-46 Target Window Limit Value
Range:
1
[1–10000
*
qc]
NOTICE
Example: When the time set in parameter 33-45 Time in
Target Window is 1000 ms, then the target window is
registered as reached 1000 ms after the position is
within the target window.
33-47 Size of Target Window
Range:
0
[0–
*
10000 qc]
NOTICE
If the target window surrounding the end position is
selected to be too small, the motor could move in a
small area around the end position, without reaching the
target window. Thus the application programme would
be stuck after the corresponding positioning command.
A target window of 0 deactivates the monitoring of the
actual position and only monitors the command
position.

Function:
The target window is read with an interval of
the time set in parameter 33-45 Time in Target
Window. The target window has been reached
when 2 consecutive readings are within the
target window set in parameter 33-46 Target
Window Limit Value.
Function:
0 = Off
Indicates the size of the target window. A
position is only viewed as reached when the
trajectory generator is finished, the actual position
is within the window, and the velocity is less than
parameter 33-46 Target Window Limit Value
(prerequisite is that both parameters 33-47 Size of
Target Window and 33-45 Time in Target Window
are activated.)
In this content the velocity is given as:
P33-46 in qc
P33-45
The controller waits to execute the next
command until the actual position is within the
target window. If this parameter is not active, the
target has been reached if the set position equals
the target position. However, this does not
necessarily correspond with the actual position of
the motor.
