Drive functions
7.3 Function modules
Target position reached (r2684.10)
The status signal "target position reached" indicates that the drive has reached its target
position at the end of a traversing command. This signal is set as soon as the actual drive
position is within the positioning window p2544 and is reset, if it leaves this window.
The status signal is not set, if
● Signal level 1 at binector input p2554 "signal traversing command active".
● Signal level 0 at binector input p2551 "signal setpoint static".
The status signal remains set, until
● Signal level 1 at binector input p2551 "signal setpoint static".
Reference point set (r2684.11)
The signal is set as soon as referencing has been successfully completed. It is deleted as
soon as no reference is there or at the start of the reference point approach.
Acknowledgement, traversing block activated (r2684.12)
A positive edge is used to acknowledge that in the mode "traversing blocks" a new traversing
task or setpoint was transferred (the same signal level as binector input p2631 activate
traversing task). In the mode "direct setpoint input / MDI for setting-up/positioning" a positive
edge is used to acknowledge that a new traversing task or setpoint was transferred (the
same signal level as binector input p2650 "edge setpoint transfer", if the transfer type was
selected using a signal edge (binector input p2649 "0" signal)).
Velocity limiting active (r2683.1)
If the actual setpoint velocity exceeds the maximum velocity p2571 - taking into account the
velocity override - it is limited and the control signal is set.
