FM 351 Positioning Function Module
EWA 4NEB 720 6001-02
Check for the correct parameterization of the FM 351 with the following
table.
Step What Must Be Done?
1
Select the Jog operating mode.
S Check that the outputs are correctly wired (type of control).
– Move forwards and backwards at creep speed.
– Move forwards and backwards at rapid speed.
S Check the encoder resolution.
– Move the drive over a defined distance in a defined direction.
The actual traversed path must match the display in the mask Test
"
Set up.
2 Select the seek-reference-point operating mode.
You check the correct synchronization of the module with the operating mode. Also, you can
check whether the software limit switches are at the correct position.
With jog move to the software limit switches Start and Finish.
The actual position must match the specified values.
The actual value must show the value of the software limit switches.
3 Now enter the incremental dimension in the increment table.
Note that only positive values are allowed for the relative incremental mode.
Save the incremental dimension.
Transfer the increment table to the FM 351.
4 Select the operating mode incremental mode:
S Absolute
– Check positioning at the defined increment.
– Check positioning at the Increments 254 and 255.
S Relative
– Check positioning at the defined increment.
– Check positioning at the Increments 254 and 255.
5 Test the other settings according to your application:
S Set reference point.
S Set actual value.
S Loop mode.
