Manual and Handwheel Travel (H1)
8.1 General characteristics of traversing in JOG
Turning, Milling, Nibbling
142 Function Manual, 11/2012, 6FC5397-1CP10-5BA0
In the case of interface signals that are only spindle-specific, while the spindle is traversing in
JOG, the following should be noted:
● The following PLC interface signals to the spindle have no effect:
– IS "Invert M3/M4" (V380x 2001.6)
– IS "Set direction of rotation ccw" or "Set direction of rotation cw" (V380x 2002.7 or .6)
– IS "Oscillation speed" (V380x 2001.5)
● The following PLC interface signals from the spindle are not set:
– IS "Actual speed cw" (V390x 2001.7)
– IS "Spindle in setpoint range" (V390x 2001.5)
Note
A reset causes the manual traverse motion (axis/spindle) to be terminated with brake
ramp.
Limitations
The following limitations are active for manual travel:
● Working-area limitation (axis must be referenced)
● Software limit switches 1 or 2 (axis must be referenced)
● Hardware limit switches
The control ensures that the traversing movement is aborted as soon as the first valid
limitation has been reached. Velocity control ensures that deceleration is initiated early
enough for the axis to stop exactly at the limit position (e.g. software limit switch). Only when
the hardware limit switch is triggered does the axis stop abruptly with "rapid stop".
An alarm is output when the corresponding limit is reached. The control automatically
prevents further movement in this direction. The traversing keys and the handwheel have no
effect in this direction.
Note
The software limit switches and working area limits are only active if the axis has previously
been referenced.
Note
The function for retracting an axis that has approached the limit position depends on the
machine manufacturer. Please refer to the machine manufacturer's documentation!
For further information on working area limits and hardware and software limit switches see
Chapter "Axis Monitoring (A3)".
