Commissioning the FM 352
FM 352 electronic cam controller

Test steps for axis synchronization and switching characteristics
The tests described in the next section help you to validate FM 352 parameter assignment.
Step Description ✔
Synchronize the axis
Incremental encoder
– Select "set reference point". To
do this enter the required value
(see chapter "Set reference
point (Page 110)").
or
– Set the "Retrigger reference
poi
nt" function switch (see
chapter "Retrigger reference
point (Page 120)").
Absolute encoder
– The FM 352 is always
synchronized immediately
following parameter
assignment.
– Adjust the absolute encoder
(see chapter "Determining
the correct absolute
encoder adjustment
(Page 82)"). You may first
have to determine the
precis
e value using the "set
reference point" function.
❑
1
Check the actual status of the axis. The physical position must match the
value output on the display.
❑
2 Check the switching characteristics of the assigned cams and tracks.
Enable testing.
Execute the "set reference point" function.
Activate cam processing.
Enable the track signals.
To do so, rotate the encoder or
set the simulation function switch.
❑
3 Test the other settings according to your application
Set reference point
Set actual value
❑
Getting prepared for programming
You still need to create the blocks required in your project.
Step Description ✔
1 Select the FMX52LIB library in SIMATIC Manager (File > Open > Libraries). ❑
2 From the program folder FM 352 CAM V2, copy the function FC 0 and the
block FB 1 to the Blocks folder.
❑
3 Create a channel DB for each module (instance DB of FB CAM_CTRL). ❑
4 If you want to use a programmed diagnostic evaluation, copy FB 2 and
create a diagnostic DB for each module.
❑
5 To write and read machine data in the user program, you require UDT3 for
16 cams, UDT4 for 32 cams, UDT5 for 64 cams, or UDT6 for 128 cams.
