PERIPHERAL DEVICE
10-4) Surge absorber (surge suppressor, surge killer)
Shown below are recommended surge suppressors (for 250 [V] or less) to be installed on peripheral
devices (magnetic contactor, solenoid value, electromagnetic brake, etc.) of the servo amplifier.
DC equipment should be equipped with a diode for surge voltage suppression.
For control relay, etc.
