Handwheel active (1 to 2)
Signal(s) from axis / spindle (NCK → PLC)
Signal(s) updated: Cyclic
These PLC interface signals provide feedback as to whether this machine
axis is assigned to handwheel 1 or 2 or is not assigned to any handwheel.
Only one handwheel can be assigned to an axis at any one time.
If several interface signals "activate handwheel" are set, then 'Handwheel 1'
has a higher priority than 'Handwheel 2'.
If the assignment is active, then the machine axis can be traversed using the
handwheel in the JOG mode.
This machine axis is neither assigned to handwheel 1 nor 2.

Plus and minus travel request
Signal(s) from axis / spindle (NCK → PLC)
Signal(s) updated: Cyclic
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.
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
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!
