Putting the FM 351 into Operation

FM 351 Positioning Module

Test and Commissioning
You can test the entries and modifications you have made in the parameter dialogs
of the configuration software.
Step What needs to be done?
1 Check your data with the dialogs Test > Commission, Test > Service and Test > Error
Evaluation.
2 You can modify incorrect machine data in the Test > Commission dialog. These
modifications are valid until the CPU next changes from STOP to RUN.
3 You can save the corrected machine data on the CPU by repeating steps 6 to 9 of the
previous table.
Testing Modes, Jobs, and Function Switches
Using the following tests you can check the correct assignment of parameters for
the FM 351.
Step What needs to be done?
1 Synchronize the axis
• Incremental Encoders
– Select “set reference point”. Enter
the corresponding value (see
Section 9.6, page 9-25).
or
– Select the “Reference Point
Approach” mode (see Section 9.3,
page 9-11).
• Absolute Encoders
– The FM 351 is synchronized
immediately after parameter
assignment.
– Make an absolute encoder
adjustment (see Section 8.6, page
8-19).
Check the actual status of the axis. The actual position must agree with the position
indicated.
2 Select the Jog operating mode.
• Check the correct interconnection of the outputs (control type) and the actual value.
– Move the axis in the plus and minus directions at creep speed.
– Move the axis in the plus and minus direction at rapid speed.
• Check the encoder resolution (see Section 8.7, page 8-22)
– Move the drive over a defined distance in a defined direction.
The actual distance traveled must match the display in the
Test > Commissioning dialog.
3 Select the operating mode incremental mode
• absolute with incremental dimension number 255
– Check the travel with the defined incremental dimension
– and adapt the switchover and switch-off differences to your system based on
incremental dimension 255.
4 Test the other function switches and jobs according to your applications
• For example loop traverse, set actual value
