YASKAWA CPS Series Technical Notes

The Evolution of CPS Series Architecture

The CPS Series was introduced alongside YASKAWA's transition from relay-logic control panels to programmable rack-based automation in the late 1980s. Early units such as the CPS-100 and CPS-120 provided single-rail DC output with manual reset overcurrent protection, designed for the CP9200 and MEMOCON GL120 controller families. As YASKAWA expanded its MP-series motion controller platform through the 1990s and 2000s, the CPS Series was updated to support dual-rail outputs and hot-swap capability in select configurations.

The CPS-150F represents the mature generation of this architecture, incorporating soft-start circuitry, LED status indication, and improved EMI filtering compliant with IEC 61000-4 standards. Compatibility across backplane generations is a known integration challenge: CPS units are keyed to specific rack form factors and connector pinouts, and substitution between sub-series (e.g., CPS-100 vs. CPS-150F) requires verification of output voltage rails, connector type, and rack slot width. As the MP900 and CP9200S platforms have entered end-of-life status, sourcing CPS Series replacements through authorized aftermarket channels has become the primary maintenance strategy for installed base operators.

• CPS-FUSE-SET: OEM fuse replacement kit compatible with CPS-100 through CPS-250 series housings
• CPS-CABLE-EXT: DC bus extension cable for inter-rack power distribution in multi-rack MP2000 systems

Quality Control for the CPS Series Range

CPS Series power supply modules present specific test challenges due to their integrated backplane connector interfaces and multi-rail DC output architecture. DriveKNMS applies the following test protocol to all CPS units prior to shipment:

• Input voltage sweep test across rated AC input range (85–264VAC) to verify regulation stability
• Full-load DC output test at rated wattage with calibrated electronic load bank, measuring output voltage deviation and ripple
• Overcurrent protection trip-point verification: unit must shut down within specification and recover on reset
• Soft-start timing measurement to confirm inrush current limiting is functional
• Backplane connector pin continuity and insulation resistance test
• Thermal soak at 50°C ambient for 30 minutes under full load to screen latent component failures
• LED status indicator functional check across normal, fault, and overload states
