7.8.3 Posion
correcon
The posion correcon takes place within a correcon window.
The posion of this window is specied via the parameters Upper correcon posion and
Lower correcon posion.
•
Upper correcon posion 40x5041:006
•
Lower correcon posion 40x5041:007
The posion is set in the unit of the measuring system used.
The Reference measuring system of correcon window parameter species whether the
posion of the correcon window relates to the corrected master posion or the posion of
the drive axis. 40x5041:005

The determined
posion error can be limited to a maximum value. This keeps acceleraons
low during the correcve movement, for instance. In order to limit the maximum value, there
is one parameter available for both the posive limit value and the negave limit value.

ters Corrected setpoint posion and Corrected setpoint velocity.
