Signal state 0 This machine axis is neither assigned to handwheel 1 nor 2.
corresponding to ... DB380x DBX4.0 to .1 (activate handwheel)
DB1900 DBX?, ff (handwheel selected)
Note for the reader Function Manual Basic Functions H1
DB390x
DBX4.5 and.4
Plus and minus travel request
Signal(s) from axis / spindle (NCK → PLC)
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 Travel is to be executed in the axis direction involved. Depending on the
mode selected, the travel command is triggered in different ways:
• JOG mode: Using the plus or minus traversing key
• REF mode: With traversing key that takes the axis to the reference
point.
• AUTO/MDI mode: A program block containing a coordinate value for the
axis in question is executed.
Signal state 0 A travel command in the relevant axis direction has not been given or a
traverse movement has been completed.
• JOG mode: The travel command is reset depending on the setting "Jog
or continuous mode".
• REF mode: When the reference point is reached.
• AUTO/MDI mode:
– The program block has been executed (and the next block does not
contain any coordinate values for the axis in question).
– Cancel using "RESET", etc.
– IS "Axis / spindle disable" is active
Application To release clamped axes (e.g. on a rotary table).
Note:
If the clamping is not released until the travel command is given, these axes
cannot be operated under continuous path control!
corresponding to ... DB380x DBX1.3 (axes/spindle disable)
DB380x DBX4.7 and .6 (plus and minus traversing key)
DB390x DBX4.7 and .6 (plus and minus travel command)

DB390x
DBX4.7 and .6
Plus and minus travel command
Signal(s) from axis / spindle (NCK → PLC)
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 Travel is to be executed in the axis direction involved. Depending on the
mode selected, the travel command is triggered in different ways.
• JOG mode: With the plus or minus traversing key
• Under REF mode: With traversing key that takes the axis to the
reference point
• AUTO/MDI mode: A program block containing a coordinate value for the
axis in question is executed.
