FM 452 Electronic Cam Controller
C79000-G7076-C452-04
Motor
The motor is controlled by the power controller and drives the spindle.
FM 452 Electronic Cam Controller
The electronic cam controller detects the current position of the axis using the
information from an encoder. The encoder signals are evaluated (for example
pulses counted) that are proportional to the distances traveled. Depending on the
actual position, the digital outputs are activated or deactivated (“cams”). The
processing stations are controlled via the digital outputs.
Encoder
The encoder supplies information both about position and direction.
CPU
The CPU executes the user program. Data and signals are exchanged between
the user program and the module using function calls.
PG/PC
You assign the required parameters and program the electronic cam controller on a
programming device or PC.
•
Parameter assignment: You set parameters for the FM 452 either using the
parameter assignment user interface or using the parameter DB.
•
Programming: You program the FM 452 with function blocks that you
incorporate directly in your user program.
•
Testing and putting into operation: You test the FM 452 using the
parameter
assignment user interface with which you also finally put the system into
operation.
