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 plus reached (r2683.7)
SW limit switch minus 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.
Stop cam minus active (r2684.13)
Stop cam plus active (r2684.14)
These status signals indicate that the STOP cam minus p2569 or STOP cam plus p2570 has
been reached or passed. The signals are reset when the cams are left in the direction other
than that in which they were approached.
Axis moves forwards (r2683.4)
Axis moves backwards (r2683.5)
Axis accelerates (r2684.4)
Drive decelerates (r2684.5)
Drive stationary (zero speed) (r2199.0)
These signals display the current motion status. If the actual absolute speed is less or equal
to p2161, then the status signal "drive stationary" is set - otherwise it is deleted. The signals
are appropriately set if jog mode, reference point approach or a traversing task is active.
