Yaskawa SGMAV Series Technical Notes

The Evolution of SGMAV Architecture

The SGMAV series is the direct successor to the SGMAS and SGMAH families within Yaskawa's Sigma servo motor lineage. The architectural transition from SGMAH (Sigma-II) to SGMAV (Sigma-V) introduced a 20-bit absolute encoder (resolution: 1,048,576 pulses/rev) as standard, replacing the 17-bit incremental encoders of the prior generation. This shift enabled absolute positioning without battery-backed homing cycles in many applications, reducing machine startup time and improving repeatability to sub-micron levels in precision axes.

The SGMAV frame design retained backward-compatible shaft and flange dimensions (IEC 72-1 compliant) with the SGMAS series in several frame sizes, allowing drop-in mechanical replacement in retrofit projects. However, the encoder connector pinout and feedback cable specifications changed between generations, requiring SGMAV-compatible cables (Yaskawa part prefix: JZSP-C) when upgrading from Sigma-II installations.

Quality Control for the SGMAV Range

Each SGMAV unit processed by DriveKNMS undergoes a structured inspection and functional test protocol specific to the Sigma-V motor architecture. The test sequence includes: insulation resistance measurement (IR test at 500VDC, minimum 100MΩ between winding and frame), winding resistance balance check across all three phases (tolerance: ±5% of nominal), encoder signal integrity verification using a Yaskawa-compatible SERVOPACK test bench (SGDV series), no-load run test at rated speed with vibration and acoustic monitoring, and brake engagement/release force measurement on brake-equipped variants (YR13 option code).

The 20-bit absolute encoder fitted to all SGMAV motors is verified for battery-backed absolute position retention and multi-turn counter integrity. Units exhibiting encoder communication errors (alarm A.810, A.820, A.830 on SGDV drives) are flagged for encoder replacement prior to dispatch. Refurbished units are re-labeled with DriveKNMS inspection date, test technician ID, and pass/fail record traceable to the unit serial number.
