Figure 180:
Positioning handshake (Single Set Value)
1
The controller has transmitted the positioning data to the drive. The data only take ef-
fect on an edge of the "New Set Value" bit.
2
The controller sets the "New Set Value" bit in the control word. The rising edge is the
request to start positioning. Since the "Single Positioning Records" mode is to be
used, the "Change Set Immediately " bit (Bit 5 of the control word) must be cleared
on the edge.
3
The drive signals that it has detected the start request by setting the set value hand-
shake. The set values have been accepted and the positioning procedure started.
The "Target Position Reached" message is canceled; likewise the Positioning Status
parameter
indicates by clearing the "Function Ended" bit that the ramp gen-
erator is issuing new values.
4
The controller cancels "New Set Value".
5
In response to the cleared "New Set Value" bit, the drive also clears the "Set Value
Handshake" bit in the status word. From this point onwards the "Set Value Reached"
message is also displayed again. It is suppressed while "New Set Value" is set.
6
The drive reaches the target position. The ramp generator reports "Function Ended",
however values can still be specified by the smoothing generator.
7
The drive reports Target Position Reached. This occurs depending on the Positioning
Window (
) and the Positioning Window Time (
) that have been set.
8
New positioning data are sent while a positioning operation is active. These data are
not taken into account until an edge of "New Set Value" has been detected.
9
The controller sets "New Set Value" even though the last positioning operation has
not ended yet. Nevertheless the data are accepted and take effect immediately.
10
The drive signals that it has detected the start request by setting the set value hand-
shake. The new set values have been accepted and were effective immediately, even
if the preceding positioning operation had not ended yet.
