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.
7.3.7 Extended setpoint channel
Description
In the servo control mode, the extended setpoint channel is deactivated by default. If an
extended setpoint channel is required, it has to be activated. The extended setpoint channel
is always activated in the vector control mode.
Properties of servo mode without the "extended setpoint channel" function module
● The setpoint is directly interconnected to p1155[D] (e.g. from a higher-level control or
technology controller)
● Dynamic Servo Control (DSC) only
When using DSC, the "extended setpoint channel" is not used. This unnecessarily uses
the computation time of the Control Unit and, for servo, can be deactivated.
● Deceleration ramp OFF1 via p1121[D]
● Deceleration ramp OFF3 via p1135[D]
● For PROFIdrive telegrams 2 to 103 and 999 only (free assignment)
● STW 1 bit 5 (freeze ramp-function generator), no function
7.3.7.1 Activation of the "extended setpoint channel" function module
The "extended setpoint channel" function module can be activated via the commissioning
Wizard or the drive configuration (configure DDS).
You can check the current configuration in parameter r0108.8. Once you have set the
configuration, you must download it to the Control Unit where it is stored in a non-volatile
memory.
