A Siemens CANopen System





Do you need a low-cost motion controller for more than 4 step or servo motors for simple non-coordinated moves? Do you need to control several valves or dispense fluids precisely?


Siemens has a solution!


Combining Siemens’ S7-1200 PLC with their SIMATIC PN/CAN Link (6BK16200AA000AA0) gives you the ability to control multiple step or servo motors with a low-cost PLC.


For example, your motor of choice is a Nanotec Smart Servo PD4, which is an integrated motor containing a controller and encoder. This motor can operate as a servo motor or a step motor. You can use up to 8 PDO’s (similar to read-write registers) on each motor and the PN/CAM Link can address 512 PDO’s. Theoretically, you could control 64 motors. However, you would be limited by the amount of PLC memory you use.


Here are the major components:


6BK16200AA000AA0 - SIMATIC PN/CAN LINK Gateway from Profinet to CAN or CANopen networks


6ES72151AG400XB0 - SIMATIC S7-1200, CPU 1215C, COMPACT CPU


PD4-C5918M4204-E-08 - Brushless DC Servo motor (stepper) with integrated controller
