Mitsubishi Electric CR1Q Series Technical Notes

The Evolution of CR1Q Architecture

Mitsubishi Electric's robot controller lineage progressed through several distinct generations before arriving at the CR1Q platform. The CR1 series (early 2000s) introduced compact controller packaging for small-payload MELFA robots, replacing rack-mounted predecessors. The CR2 and CR2Q variants expanded I/O capacity and introduced open-network compatibility via CC-Link and Ethernet/IP. The CR3 series (introduced circa 2013) brought 64-bit processing, enhanced safety circuit integration (IEC 62061 / ISO 13849-1 PLd compliance), and a unified RT ToolBox3 programming environment. The CR1Q represents a refined compact-class controller within the CR3-generation architecture, retaining backward compatibility with MELFA BASIC V/VI programming while supporting RT ToolBox3 and iQ Works integration. Key compatibility considerations: CR1Q controllers are not backward-compatible with CR1/CR2 teach pendants without adapter hardware. Network modules designed for CR3D are generally cross-compatible with CR1Q via the same slot architecture. As the CR1Q series has entered its mature lifecycle phase, Mitsubishi has introduced the CR800 series as the designated successor platform, making long-term spare parts sourcing for CR1Q a critical operational requirement for facilities with existing installations.
