Information
Note that I297 Maximum speed position encoder must be parameterized according to your application case. If I297 is set
too low, the permitted maximum speed is exceeded even at normal operating speeds. On the other hand, if I297 is set too
high, measuring errors of the encoder can be overlooked.
I297 depends on the following parameters: I05 Type of axis, I06 Decimal places position, I09 Measure unit as well as
I07 Distance factor numerator position and I08 Distance factor denominator position for Drive Based or A585 Feed constant
for CiA 402. If you have made changes to one of the parameters listed, select I297 accordingly as well.

Parameterizing the position and velocity window
Enter position limits and velocity zones for set values. To do so, parameterize boundary values for reaching a position or
velocity.
1.
Select the
Axis model
wizard >
Window position, velocity
.
2.
C40 Velocity window:
Parameterize a tolerance range for velocity tests.
3.
I22 Target window:
Parameterize a tolerance range for position tests.
4.
I87 Actual position in window time:
Parameterize how long a drive must stay in the specified position range before a corresponding status message is
output.
5.
A546 Following error window
Parameterize a tolerance range for lag tests.
8.1.4.6
Limiting the axis
The tasks of a controller include setting axis limits and monitoring them. The set values necessary for this are parameterized
in the controller and transmitted to the individual drive controller. Note that, for this reason, the set values of the controller
are not negatively affected by the individually configured values on the drive controller side.
Limiting the position (optional)
1.
Highlight the relevant drive controller in the project tree and click on the first projected axis in the project menu >
Wizard
area.
2.
Select the
Axis model
wizard >
Limit: Position
.
3.
If necessary, limit the position of your axis using a software or hardware limit switch to secure the travel range.
