Dwell Time (G4) - Siemens Sinumerik 840D sl Programming Manual

● Link and container axes
Travel to fixed stop is also permitted for link and container axes.
The status of the assigned machine axis is maintained beyond the container rotation. This
also applies for modal torque limiting with FOCON.

● If the torque limit is reduced too far, the axis will not be able to follow the specified setpoint;
the position controller then goes to the limit and the contour deviation increases. In this
operating state, an increase in the torque limit may result in sudden, jerky movements. To
ensure that the axis can follow the setpoint, check the contour deviation to make sure it is
not greater than the deviation with an unlimited torque.

Dwell time (G4)

G4 can be used to program a "dwell time" between two NC blocks during which workpiece
machining is interrupted.
Note
G4 interrupts continuous-path mode.
