1. While cleaning with air, confirm that there is no oil content and/or moisture in the air.
2. This inspection and replacement period is when water- or oil-proof functions are required.
3. The life expectancy of the battery is approximately 2 years, when its power is OFF throughout the year. For
replacement, a lithium battery (ER3V: 3.6V, 1000mAh) manufactured by Toshiba Corp. is recommended.

1. Condenser for smoothing the main circuit
If the servo amplifier is in use for more than 3 years, contact the dealer or sales office.
The capacity of the condenser for smoothing the main circuit is reduces due to the frequency of
motor output current and power ON/ OFF during usage, and it may cause damage.
