Starting up the FM 354
Note
To start a movement, we recommend the following input sequence:
You can operate the "R+" and "R–" buttons in the "jogging" mode as fol-
lows:
1. Select "R+" or "R–" with the mouse
2. Press the space bar
You can operate "Start" and "Stop" with the mouse, or with the space bar if
you have already selected the button.
The digital outputs are not set in the "Stop" status of the CPU.
When you operate the following buttons, you will get dialog windows:
Warning
!
If you move the axis directly (without simulation), for safety's sake make
sure you can switch off the hardware if a hazard arises.
Note
If you use the start–up user interface to operate the FM 354 when the CPU is
in "STOP", and then switch the CPU to "RUN" and then immediately switch
to the start–up interface in your user program by means of the [TFB]
(TEST_EN) signals (e.g. if example application 3 is included in the user
program), please note the following:
You must select the mode again from the start–up interface, or close the
start–up interface and call it up again.
