H1: Manual and handwheel travel
4.5 Incremental manual travel
● When the first valid limit is reached
● Deselection or change of the current increment (e.g. change from INC100 to INC10)
● When faults occur (e.g. on cancellation of the servo enable)
Risk of collision
If "continuous" mode is selected, several axes can by started by pressing and releasing the
relevant direction key. Any interlocks must be implemented via the PLC!
Note
While an axis is moving, a change of mode from JOG to AUTOMATIC or MDI is not permitted
within the control.
Interface signals
Selection
Incremental traversing in JOG mode must be activated via the PLC interface:
● Machine axes:
– DB31, ... DBX5.0 - 5.5 (request of the machine function: INC1 to INCvar)
● Geometry axes:
– DB21, ... DBX13.0-5 (geometry axis 1: machine function request: INC1 to INCvar)
– DB21, ... DBX17.0-5 (geometry axis 2: machine function request: INC1 to INCvar)
– DB21, ... DBX21.0-5 (geometry axis 3: machine function request: INC1 to INCvar)
● Orientation axes:
– DB21, ... DBX321.0-5 (orientation axis 1: machine function request: INC1 to INCvar)
– DB21, ... DBX325.0-5 (orientation axis 2: machine function request: INC1 to INCvar)
– DB21, ... DBX329.0-5 (orientation axis 3: machine function request: INC1 to INCvar)
