Canceling the Setting
With the setting ”Cancel set actual value”, you reset the coordinate displacement
that resulted from “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 rising edge at input I1. However, it can be overwritten by a
new “set actual value on-the-fly”.
During a module start up, these settings are reset.

Possible Sources of Error
“Set actual value on-the-fly” and “Retrigger reference point” must not be executed
at the same time.
With the setting “set actual value on-the-fly”, an error can be signaled if the setting
means that a software limit switch would be exceeded with the rising edge at I1.
This operating error is signaled by a diagnostic interrupt and entered in the
diagnostic buffer.
