Interface signalsWhen manually traversing the spindles, the interface signals between NC and PLC have thesame effect as for the machine axes.The interface signals DB31, ... DBX60.7 or DBX60.6 (position reached with fine or coarse exactstop) are only set if the spindle is in position control.Spindle-specific interface signalsIn JOG mode, the following interface signals to the spindle have no effect:● DB31, ... DBX17.6 (invert M3/M4)● DB31, ... DBX18.6 - 7 (oscillation rotation direction, right/left)● DB31, ... DBX18.5 (oscillation enable)● DB31, ... DBX16.7 (delete S value)In JOG mode, the following interface signals from the spindle are not set:● DB31, ... DBX83.7 (clockwise actual direction of rotation)● DB31, ... DBX83.5 (spindle in setpoint range)17.8 Manual traversing of geometry axes/orientation axesSimultaneous travelOnly one geometry axis can be traversed continuously or incrementally at one time using thetraversing keys. Where an attempt is made to traverse more than one geometry axis, alarm20062 "Axis already active" is output. However, three geometry axes can be traversedsimultaneously using handwheels 1 to 3.Transverse axisIf a geometry axis is defined as transverse axis (see MD20100 $MC_DIAMETER_AX_DEF)and radius programming has been selected, the following applies:● Continuous travel:There are no differences when a transverse axis is traversed continuously.● Incremental travel:Only half the distance of the selected increment size is traversed. For example, with INC10the axis only traverses 5 increments when the traversing key is pressed.● Traversing with the handwheel:As for incremental travel, with the handwheel only half the distance is traversed perhandwheel pulse.References:Function Manual Basic Functions; Transverse Axes (P1)H1: Manual traversing17.8 Manual traversing of geometry axes/orientation axesAxes and spindles668 Function Manual, 06/2019, A5E47437747B AA
