4 Configuration and Wiring
Surge Absorber
• Use a surge absorber to absorb the lightning surge voltage and the abnormal voltage from the power
input line.
• The following table gives the recommended surge absorber specifications.
Servo Drive voltage
Single-phase 100 VAC
Single-phase 200 VAC
3-phase 200 VAC
3-phase 400 VAC
Note 1. Refer to the catalogs from the manufacturer for how to use.
2. The surge current tolerance is the value for the standard impulse current of 8/20 μs. For a greater pulse
width, reduce the current or change the surge absorber to the one with a higher capacity.
3. Select a CSA-certified product when you use a surge absorber.
