Status signals

The status signals relevant to positioning mode are described below.
Tracking mode active (r2683.0)
The "Follow-up active mode" status signal shows that follow-up mode has been activated
which can be done by binector input p2655 (follow-up mode) or by a fault. In this status, the
position setpoint follows the actual position value, i.e. position setpoint = actual position
value.
Setpoint static (r2683.2)
The status signal "setpoint static" indicates that the setpoint velocity has a value of 0. The
actual velocity can deviate from zero due to a following error. While the status word has a
value of 0, a traversing task is being processed.
Traversing command active (r2684.15)
The status signal "traversing command active" indicates that a traversing command is active.
A motion command should be understood to comprise all motions (including jog, setup etc.).
Contrary to the status signal "setpoint static", the status signal remains active - e.g. if a
traversing command was stopped by a velocity override or intermediate stop.
SW limit switch + reached (r2683.7)
SW limit switch - reached (r2683.6)
These status signals indicate that the parameterized negative p2578/p2580 or positive
p2579/p2581 traversing range limit was reached or passed. If both status signals are 0, the
drive is located within the traversing limits.
