H1: Manual and handwheel travel
4.6 Handwheel travel
Note
It is only permissible to change the inversion signal at standstill. If the change is made while
motion setpoints are being output by the interpolator, then the signal change is rejected and
an alarm is output; further, motion is stopped taking into account the actual acceleration value.
Abort/interruption of the traversing motion
The following NC/PLC interface signals abort the traversing motion. The setpoint/actual-value
difference is deleted.
NC/PLC interface signal
DB21, ... DBX7.7 (NC reset)
DB21, ... DBX12.0-2 (geometry axis 1: Activate hand‐
wheel <n>)
DB21, ... DBX16.0-2 (geometry axis 2: Activate hand‐
wheel <n>)
DB21, ... DBX20.0-2 (geometry axis 3: Activate hand‐
wheel <n>)
DB21, ... DBX6.2 (delete distance-to-go)
DB31, ... DBX2.2 (delete distance-to-go / spindle reset) Geometry axis / machine axis
DB31, ... DBX4.2 (activate handwheel <n>)
DB31, ... DBX1.3 (axis/spindle disable)
DB31, ... DBX1.5 (position measuring system 1)
DB31, ... DBX1.6 (position measuring system 2)
The effect of the handwheel travel (abort or interruption of the traversing motion) can be set
for other NC/PLC interface signals (stop signals) (see Section "Parameter assignment
(Page 173)").
NC STOP only interrupts the traversing movement. Any setpoint/actual-value difference is
retained. The distance-to-go is then traversed using NC START.
