DB31, ...DBX1.3 Axis/spindle disableRegarding N40: Axis X traverses from the last position (approx. 20 mm) to the programmedposition 200 mm.● Effects of "Axis/spindle disable" for spindle or axis couplings:LS/LA1) FS/FA2) Coupl.3) Effect0 0 Off Setpoints are output0 1 Off No setpoint output for following spindle/axis1 0 Off No setpoint output for leading spindle/axis1 1 Off No setpoint output for leading and following spindle/axis0 0 On Setpoints are output0 1 On Axis/spindle disable has no effect on the FS/FA1 0 On Axis/spindle disable also has an effect on the FS/FA1 1 On No setpoint output1) Status of the interface signal DB31, ... DBX99.0 (leading spindle/axis active)2) Status of the interface signal DB31, ... DBX99.1 (following spindle/axis active)3) Status of the coupling between leading and following spindle/axisSignal state 0 The reset of the interface signal does not take effect until the axis/spindle is stationary.Axis● Setpoints are output on the position controller again immediately after the reset of the interfacesignal.Spindle● After the reset of the interface signal, the spindle disable which is still effective internally must becancelled by an axis-specific reset, channel reset or end of program (M30/M2). Only then aresetpoints output on the speed controller again.Application exam‐ple(s)Prevention of traversing motions of the axis/spindle when running-in an NC program.Corresponding to ... DB21, ... DBX33.7 (program test active)Additional references Behavior in synchronous mode:Function Manual, Extended Functions; Synchronous Spindle (S3)DB31, ...DBX1.4 Follow-up modeEdge evaluation: No Signal(s) updated: CyclicallySignal state 1 Follow-up mode is active:● The position setpoint is continuously tracked: Position setpoint = actual position value● Feedback signal: DB31, ... DBX61.3 = 1 (follow-up active)● Standstill and clamping monitoring are not active.● If an NC program is active when the closed-loop control system is switched on again, a control-internal repositioning operation is performed (REPOSA: Linear approach with all axes) to the lastprogrammed position.NoteFollow-up mode is only useful with a simultaneous reset of the controller enable: DB31, ...
