Canceling the setting
The "Cancel set actual value" can be used to reset the coordinate shift caused by "Set actual
value" or "Set actual value on-the-fly".
Once "set actual value on-the-fly" has been triggered, it can no longer be deleted before
execution by a positive edge at input I1. However, it can be overwritten by a new "Set actual
value on-the-fly".
These settings will be reset at the next start of the module.

35.2 AVALREM_EN BOOL FALSE 1: Cancel actual value setting
Possible causes of error
"Set actual value on-the-fly" and "Retrigger reference point" may not be executed in parallel.
The "set actual value on-the-fly" can be monitored in order to signal an operating error if this
setting causes a software limit switch to exceed the permissible traversing range at a
positive edge at input I1. This operating error is signaled by a diagnostic interrupt, and
written to the diagnostic buffer.
