Direct output 1 (r2683.10)
Direct output 2 (r2683.11)
If a digital output is parameterized, the function "direct output 1" or "direct output 2", then it
can be set by a corresponding command in the traversing task (SET_O) or reset
(RESET_O).
Following error in tolerance (r2684.8)
When the axis is traversed, closed-loop position controlled, using a model, the permissible
following error is determined from the instantaneous velocity and the selected Kv factor.
Parameter p2546 (dynamic following error monitoring tolerance) defines a dynamic following
error window that defines the permissible deviation from the calculated value. The status
signal indicates as to whether the following error is within the window (status 1).
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 inside the positioning window (p2544). The signal is reset when the positioning
window is exited.
The status signal will not be set under the following conditions:
● A "1" signal is present at the binector input p2554 (message traversing command active).
● A "0" signal is present at the binector input p2551 (message setpoint stationary).
The status signal remains set until a "1" signal is present at the binector input p2551
(message setpoint stationary).
Reference point set (r2684.11)
The signal is set as soon as referencing has been successfully completed. It is reset when
reference point approach is started.
Acknowledgement, traversing block activated (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 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 – then it is limited and the status signal is set.
