10.5 Surge Absorber
 For protection from lightning surge
Install a surge absorber to protect servo system from the surge approaching from the power
line (induced lightning surge).
Serge absorber absorbs lightning surge, preventing malfunction or damage of a servo
system.
Recommendation [Soshin Electric product
］
Single phase: LT-C12G801WS *
Three-phase: LT-C32G801WS
* The product for single phase has no L2 terminals.
 For protection from open/close surge of peripheral equipment
To install a surge absorber to peripheral equipment (electromagnetic contactor, solenoid,
electromagnetic brake, etc.) of the servo amplifier, use the following one.
When an inductive load such as the clutch and solenoid is turned off, a counter electromotive
force of several hundreds or several thousands of volts [V] is generated. The surge absorber
suppresses the surge voltage.
For DC devices, install a diode to suppress the surge voltage.
