Supplementary manual for Yaskawa Σ-7S/Σ-7W servo units covering application functions, adjustment, monitoring, and maintenance.
This supplementary manual provides additional information for the Σ-7 series AC servo drives, specifically the Σ-7S and Σ-7W servo units. It should be used together with the main product manuals to correctly operate and maintain the devices.
The document details application functions such as speed control, forced‑stop, A‑type vibration suppression and speed‑ripple compensation, explains adjustment procedures, describes monitoring of product life and alarm handling, and gives maintenance and part‑replacement guidelines. This manual is written in Chinese.

The forced‑stop input (FSTP) signal can be set and the method of stopping can be selected as described in sections 1.2.1‑1.2.3.
It provides a method to control multiple vibrations and includes related parameters, as outlined in the A 型抑振控制功能概要 section.
Use the monitoring section (3.1) which lists monitorable items and provides step‑by‑step procedures for product‑life monitoring.
