19.1.9 Signals from axis/spindle (DB31, ...)
DB31, ...
DBX61.0 Drive test travel request
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 The control signals that all of the traversing conditions for the drives are fulfilled.
Prerequisites for this are:
• The mechanical brake of the axis involved was previously released and all other axis traversing
conditions are fulfilled.
With:
DB31, ... DBX61.0 (drive test, travel request) = 1 signal
the appropriate axes can be moved.
• The axis disable:
DB31, ... DBX1.3 (axis/spindle disable) = 1 signal
is not active.
Signal state 0 The control signals that the axes cannot be moved.
Axes cannot be moved for:
• DB31, ... DBX61.0 (drive test, travel request) = 0 signal
• in the control when faults are present
This means that the prerequisites specified above are not fulfilled.

DBX61.3 Followup mode active
Edge evaluation: no Signal(s) updated: Cyclic
Signal state 1 The control signals that the followup mode for the axis/spindle is not active.
Prerequisites for this are:
• The controller enable for the drive has been withdrawn (either by the PLC with "controller enable
" = 0 signal or inside the control for faults; refer to the references)
• Follow-up operation is selected (either by the PLC with IS "follow-up operation" = 1 signal or in
the control, e.g. when withdrawing the controller enable from an axis that is moving)
The position setpoint continually tracks the actual value while the follow-up mode is active.
Zero speed and clamping monitoring are not active.
Signal state 0 The control signals that followup mode for the axis/spindle is not active.
Zero speed and clamping monitoring are active.
This means that the prerequisites specified above are not fulfilled.
In the "hold" state, the interface signal:
DB31, ... DBX61.3 (follow-up mode active)
is 0.
Special cases,
errors, ....
Notice:
A delete distancetogo is triggered internally in the control on transition from "Follow up" to "Hold"
(IS "Followup mode" = 0) or in the closed-loop control mode (IS "Controller enable" = 1).
Corresponding to ... DB31, ... DBX2.1 (controller enable)
DB31, ... DBX1.4 (follow-up mode!)
