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.
