The teach-in data and reference values are also reset if the system, application and/or tuning parame-
ters, which are always the same, are transferred from the higher-order controller at system start but
have never been saved as persistent data on the Motion Terminal controller.
In this case, the Motion Terminal starts with the default values for the parameters. As soon as they are
overwritten by the higher-order controller, the change to the parameters causes the teach-in data and
reference values to be discarded.
To prevent this behaviour, the system, application and/or tuning parameters must be saved once as
persistent data on the Motion Terminal controller. This ensures that, when the higher-order controller
transfers the parameters, which are always the same, no change can be detected between the saved
and transferred values.
For special requirements, it may be the case that previously determined teach-in data need to be
retained after the system, application and/or tuning parameters were changed. For this purpose, the
option "Retention of existing teach-in data for parameter changes" can be set in the settings for the
Motion Terminal.
The setting is executed via the menu for the WebConfig interface or the transfer mode in channel 14
(

Tab. 59 Meaning of the indices per addressed target and channel). With a parameter change, the
teach-in data are subsequently no longer reset automatically, but a message is entered once into the
malfunction list. When this option is activated, it is crucial that the user ensures that the actuated
parameter changes in combination with the existing teach-in data cannot lead to undesired behaviour
of the drive.
