Other information
· When the control is switched on, the axes can be traversed right
up to the limits of the machine as the reference points have not yet
been approached and the axes referenced. Emergency limit
switches might be triggered as a result.
· The software limit switches and the working area limitation are not
yet operative !
· The feedrate enable must be set (FST display must not light up in
the program control display).
Machine manufacturer
If it is not meaningful to traverse several axes simultaneously, the
machine manufacturer must provide an interlock in the PLC program.
Function
The "Inc" (Increment) function can be used to enter a settable
increment value for Inc variable traversing.
Operating sequence
"Jog" mode is selected in the "Machine" operating area.
The "Increment" window appears on the screen.
Enter the desired increment size.
Press this key in manual mode together with the "Axis" key to traverse
the axis in increments of the size set above in the appropriate
direction (see also Section "Traversing axes").
Increment keys with preset increment sizes are temporarily
inoperative.
