When Using an Incremental Encoder
*1. The incremental encoder pin numbers for wiring the connector depend on the Servomotor that you use.
*2. represents a shielded twisted-pair cable.
• When Installing a Battery on the Encoder Cable
Use the Encoder Cable with a Battery Case that is specified by Yaskawa.
Refer to the following manual for details.
Σ-7-Series Peripheral Device Selection Manual (Manual No.: SIEP S800001 32)
• When Installing a Battery on the Host Controller
Insert a diode near the battery to prevent reverse current flow.
