RRO (Request-Response Option)
These bits determine the behavior when passing controlword 6040
bit 5 ("new setpoint") –
in this case, the controller releases the bit itself. This eliminates the need to externally reset
the bit to "0" afterwards. After the bit is set to the value "0" by the controller, bit 12 ("setpoint
acknowledgment") is also set to the value "0" in statusword 6041
.
Note
These options cause the controller to modify object controlword 6040
.

The controller releases the "new setpoint" bit as soon as the current
targeted movement has reached its target.

RADO (Rotary Axis Direction Option)
These bits determine the direction of rotation in "Profile Position" mode.
Bit 7
Bit 6
Definition
0
0
Normal positioning similar to a linear axis: If one of the "Position Range
Limits" – 607B
h
:01
h
and 02
h
– is reached or exceeded, the preset is
automatically transferred to the other end of the limit. Only with this bit
combination is a movement greater than the modulo value possible.
0
1
Positioning only in negative direction: If the target position is greater than
the current position, the axis moves to the target position via the "Min
Position Range Limit" from object 607D
:01
h
.
1
0
Positioning only in positive direction: If the target position is less than
the current position, the axis moves to the target position via the "Max
Position Range Limit" from object 607D
:01
h
.
1
1
Positioning with the shortest distance to the target position. If the
difference between the current position and the target position in a 360°
system is less than 180°, the axis moves in the positive direction.
