Target position reached (r2684.10)
The "Target position reached" status signal indicates that the drive has reached its target
position at the end of a motion command. This signal is set as soon as the actual drive
position is inside the positioning window p2544. The signal is reset when the positioning
window is exited.
The status signal is not set if
● signal level 1 is present at binector input p2554 "Motion command active message".
● signal level 0 is present at binector input p2551 "Setpoint stationary message".
The status signal remains set, until
● signal level 1 is present at binector input p2551 "Setpoint stationary message".
Reference point set (r2684.11)
The signal is set as soon as a homing process has been successfully completed. It is
canceled as soon as a reference is no longer present or when homing is started.
Traversing block acknowledgement active (r2684.12)
A positive edge is used to acknowledge that a new motion command or setpoint has been
accepted in "Traversing blocks" mode (same signal level as for binector input p2631
(activate traversing block)). In "Direct setpoint specification / MDI for setup/positioning"
mode, a positive edge is used to acknowledge that a new motion command or setpoint has
been accepted (same signal level as for binector input p2650 "Edge setpoint acceptance" if
the type of acceptance has been selected via an edge (binector input p2649 "0" signal)).
Speed limitation active (r2683.1)
If the current setpoint velocity exceeds the maximum velocity p2571 taking into account the
velocity override, it is limited and the control signal is set.
