%X Most motion control systems for mechatronic systems are
implemented on digital computers. In this paper we present
an FPGA based solution implemented on a low cost Xilinx
Spartan III FPGA. A Production Cell setup with multiple
parallel operating unit is chosen as test case. The embedded
control software for this system is designed in gCSP using a
reusable layered CSP based software structure. gCSP
is extended with automatic Handel\-C code generation for
configuring the FPGA. Many motion control systems use
floating point calculations for the loop controllers. Low
cost general purpose FPGAs do not implement hardware\-based
floating point units. The loop controllers for this system
are converted from floating point to
integer\-based calculations using a stepwise refinement
approach. The result is a completely FPGAbased motion
control system with better performance figures than previous
