Adjusting spindle speed and feed rate
With the potentiometers you can vary the spindle speed S and feed
rate F from 0 % to 150 % of the set value.
The feed rate potentiometer only lowers the programmed feed
rate, not the feed rate calculated by the control.
The override for spindle speed is only functional on
machines with infinitely variable spindle drive.
Feed rate limit F MAX
Refer to your machine manual.
The feed-rate limit depends on the machine.
The
F MAX
soft key enables you to reduce the feed rate speed for
all operating modes. The reduction applies to all rapid traverse and
feed rate movements. The value you enter remains active after
switch-off or switch-on.
The
F MAX
soft key is available in the following operating modes:
Program run, single block
Program run, full sequence
Positioning w/ Manual Data Input
Procedure
To activate the feed rate limit F MAX, proceed as follows:
Operating mode: Press the
Positioning w/ Manual Data Input
key
Press the
F MAX
soft key
Enter the desired maximum feed rate
Press the OK soft key
