Yaskawa SGMSH Series Technical Notes

The Evolution of SGMSH Architecture

The SGMSH series was introduced as part of Yaskawa's Sigma-II platform in the late 1990s, succeeding the Sigma-I (SGMD/SGMG) generation. The core architectural advancement was the integration of a 17-bit incremental encoder (standard) and optional 17-bit absolute encoder, replacing the earlier 13-bit resolvers. This increased positioning resolution from 8,192 pulses/rev to 131,072 pulses/rev, enabling sub-micron repeatability in precision axes.

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.

Compatibility note: SGMSH motors require SGDH-series SERVOPACKs with matching capacity codes. They are not directly interchangeable with Sigma-V (SGMGV) or Sigma-7 (SGMGV7) motors without drive replacement, due to encoder protocol differences (MECHATROLINK-II vs. MECHATROLINK-III). For facilities planning long-term maintenance, DriveKNMS maintains cross-reference documentation for upgrade path planning.

Sourcing Hard-to-Find & Obsolete SGMSH Parts

Q: How is condition confirmed before quotation?
A: Available condition, photos, test records and documentation are checked according to the requested model and sourcing channel before a formal RFQ response.

Quality Control for the SGMSH Range

Each SGMSH unit processed by DriveKNMS undergoes a structured inspection protocol specific to the Sigma-II motor architecture:
