Presetting the travel movement feedback
The feedback messages can be enabled and programmed separately for each output. The status feedback
can be used as an active signalling object or as a passive status object. As an active signalling object, the
status feedback information is transmitted to the bus whenever the object value changes. As a passive
status object, there is no telegram transmission after a change. In this case, the object value must be read
out. The ETS automatically sets the object communication flags required for proper functioning.
With an active signalling object, the feedback telegram can be transmitted after bus voltage return with a
time delay to reduce the bus load, with the delay being preset globally for all outputs in common (cf. "Delay
after bus voltage return").
The feedback functions of an output must be enabled on parameter page "Ax – Enabled functions" (x =
number of output). Only then are the parameters for the feedback functions visible.
Set the parameter "Travel movement feedback" on parameter page "Ax – Feedbacks" to "feedback
object is active signalling object".
The feedback object is enabled. A telegram is transmitted when the connected drive starts moving or
stops.
Set the parameter "Travel movement feedback" on parameter page "Ax – Feedbacks" to "feedback
object is passive status object".
The feedback object is enabled. A telegram representing the current travel movement will be transmitted
in response only if the feedback object is read out by the bus.
The feedback function must be preset as actively transmitting function.
If a time delay after bus voltage return should be necessary, the parameter "Time delay for feedback
after bus voltage return" on parameter page "Ax – Feedbacks" must be set to "yes"
A travel movement feedback telegram is transmitted with a time delay after bus voltage return, for
instance, when the drive is set in motion as a result of the preset behaviour after bus voltage return. After
the end of the time delay, the object value state last adjusted will be transmitted to the bus. No feedback
telegram is transmitted during a running delay. This is also the case if the drive stops or starts moving
during this delay.
Automatic transmission after bus voltage return will take place only if the drive starts moving on return of
bus voltage or if there has been a change of the travel movement caused by the bus failure.
