Bit 7, 6
Plus and minus traversing command
Signal state 1 or
edge change 0 → 1
A traverse movement of the axis is to be executed in one or the other direction.
Depending on the mode selected, the command is triggered in different ways:
• JOG mode:
With the plus or minus traverse key.
• REF mode:
With the traverse key that takes the axis to the reference point.
• AUT/MDA mode:
A program block containing a coordinate value for the axis in question is executed.
Signal state 0 or
edge change 1 → 0
A traversing command in the relevant axis direction has not been given or a traverse movement
has been completed.
• JOG mode:
The traversing command is reset depending on the current setting "jog or continuous mode"
(DB31, ... DBX4.7 and/or DBX4.6).
While traversing with the handwheel.
• REF mode:
When the reference point is reached.
• AUT/MDA mode:
The program block has been executed (and the next block does not contain any coordinate
values for the axis in question).
Cancel by "RESET", etc.
DB21, … DBX25.7 (axes disable) is active.
Application
example(s)
To release clamping of axes with clamping (e.g. on a rotary table).
Note:
If the clamping is not released until the traversing command is given, these axes cannot be
operated under continuous path control!

Active machine function INC1, ..., continuous
Edge evaluation: no Signal(s) updated: Cyclic
Signal state 1 or
edge change 0 → 1
The PLC interface receives a signal stating which JOG mode machine function is active for the
machine axes.
The reaction to actuation of the traverse key or rotation of the handwheel varies, depending on
which machine function is active.
Signal state 0 or
edge change 1 → 0
The machine function in question is not active.
Corresponding to ... DB31, ... DBB5 (machine function INC1, ..., continuous)
