Plus and minus travel request (for axis in the Work)
Signal(s) from channel (NCK → PLC)
Signal(s) updated: Cyclic
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 actual setting "Jog or
continuous mode".
While traversing with the handwheel.
● Under REF mode: When the reference point is reached
● AUT/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 disabled" is active.

DB3300 DBX1008.7 or .6 (travel command plus and travel command minus)
Travel command plus and minus
for axis 1 in the Work

Signal(s) from channel (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: 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.
A travel command in the relevant axis direction has not been given or a
traverse movement has been completed.
● JOG mode:
– Withdrawing the traversing key
– When ending traversing with the handwheel.
● Under 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 disable" is active
