Handwheel Traversal In Jog - Siemens SINUMERIK 808D Function Manual

● A variable increment (INCvar). The increment setting for the variable increment can also be made for all axes using
general SD41010 JOG_VAR_INCR_SIZE (size of the variable increment for INC/handwheel).
Traverse keys and travel command
As for continuous traversing (see Section "Continuous travel (Page 62)")
Abort traversing movement
If you do not want to traverse the whole increment, the traverse movement can be aborted with RESET or "Delete distance-
to-go" interface signal (DB380x.DBX0002.2).

Handwheel traversal in JOG

Selection
"JOG" mode must be active. The user must also set the increment INC1, INC10, etc., which applies to handwheel travel.
Up to 2 handwheels can be connected. This means that up to 2 axes can be traversed by handwheel simultaneously and
independently.
A handwheel is assigned to the geometry or machine axes (WCS or MCS) via interface signals.
The axis to be moved as a result of rotating handwheel 1 to 2 can be set:
● Via the PLC user interface with IS "Activate handwheel 1 to 2"
– For machine axis (traverse in MCS): DB380x.DBX0004.0 to .2
– For geometry axis (traverse in WCS): DB3200.DBX1000.0 to .2, DB3200.DBX1004.0 to .2, DB3200.DBX1008.0 to .2.
The assignment is linked to the PLC interface through the PLC user program. Only here can several machine axes be
assigned to one handwheel simultaneously.
● Using menu-assisted operation (HMI).
Pressing the following softkey in "JOG" mode displays the "Handwheel" window:
This enables an axis (WCS or MCS) to be assigned to each handwheel.
A separate user interface between the HMI and PLC is provided to allow activation of the handwheel from the operator panel
(HMI). This interface that the basic PLC program supplies for handwheels 1 to 2 contains the following information:
● The axis numbers assigned to the handwheel IS "Axis number handwheel n"
(DB1900.DBB1003, ff)
● Additional information on the machine or geometry axis
IS "Machine axis" (DB1900.DBB1003.7, ff)
The "Activate handwheel" interface signal is either set to "0" (disable) or to "1" (enable) by the PLC user program for the
defined axis.
Settings as path or velocity
When the electronic handwheel is turned, the assigned axis is traversed either in the positive or negative direction
depending on the direction of rotation.
The general MD11346 HANDWH_TRUE_DISTANCE (handwheel path or velocity specification) can be used to set the
setting type of the handwheel motion and thus adapted to the intended use.
● MD value = 0 (default):
The settings from the handwheel are velocity specifications. When the handwheel is stationary, braking is realized along
the shortest path.
● MD value = 1:
The settings from the handwheel are path specifications. No pulses are lost. Limiting the velocity to the maximum
permissible value can cause the axes to overtravel. Particular care should be taken in the case of a high weighting of the
handwheel pulses. Further variants of the path or speed setting are possible with the value = 2 or 3.
