When migrating older systems to this CPU, ensure that your existing MR-J3 servo amplifiers are either configured for SSCNET III\/H compatibility mode or upgraded to MR-J4 models. Note that the program structure under MT Developer2 differs slightly from the legacy MT Developer format; mechanical system programs must be converted to the newer Motion SFC (Sequential Function Chart) structure to run correctly on this controller hardware.\u003c\/p\u003e\n\n\u003ch4\u003eApplication Pitfalls \u0026amp; Engineering Notes\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eWhen utilizing all 32 axes under complex electronic cam or phase compensation structures (SV22), pay close attention to the operation cycle settings in MT Developer2. If the operation cycle is set too low (e.g., 0.222 ms) and CPU processing exceeds 100%, watchdog timer errors or synchronous communication dropouts will occur. For heavy multi-axis coordination, consider balancing processing load by extending the operation cycle to 0.444 ms or 0.888 ms.\u003c\/p\u003e\n\n\u003ch4\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eSSCNET III\/H uses specialized plastic optical fiber (POF) cables. Ensure the minimum bending radius of these optical cables is never compressed below 25 mm. Sharp bends or over-tightened cable zip-ties will cause signal degradation, resulting in intermittent SSCNET loop initialization failure and AL.37 (Parameter Error) or AL.3c (Communication Error) faults on connected MR-J4 servo drives.
