2.3.2 Surge Absorbers
A surge absorber absorbs the energy that is stored in the coil of an inductive load to suppress noise. Always
use surge absorbers or diodes on all inductive loads that are connected near the Σ-V-SD servo driver. (Induc-
tive loads include magnetic contactors, magnetic relays, magnetic valves, solenoids, and magnetic brakes.)
2.3.3 Absolute Encoder Battery
Use the BA518 battery for absolute encoders. This battery can be obtained from Yaskawa Controls Co., Ltd.

• Select a surge absorber with a capacity that is sufficient for the coil in the inductive
load.
• Always install surge absorbers. If you do not install surge absorbers, the surge volt-
age from the coil that occurs when the inductive load is turned ON and OFF will affect
the SERVOPACK control signal lines and could cause incorrect signals.
CAUTION
•Purchase a battery for the absolute encoder separately and mount it on the power regeneration converter.
•A lithium battery is used for the absolute encoder. Confirm the most current IATA dangerous goods regula-
tions before transporting the battery as air cargo.
