6.3. Operating Conditions
Ambient Temperature: annual average 30
°
C
Load factor: 80% max.
Operation rate: 20-hours/day max.
6.4. Replacing Battery for Absolute Encoder
Battery replacement is only required for servo systems using an absolute
encoder. When battery voltage is 2.7V or less, XtraDrive outputs absolute
encoder battery alarm (A.83, when using Yaskawa
∑
-II motors with absolute
encoder) only when the XtraDrive power is ON, but not while XtraDrive is
operating.
6.4.1. Recommended Battery
Lithium battery: ER6VC3, manufactured by Toshiba Battery Co. Ltd.,
3.6 2000mAh or other compatible lithium battery.
Battery kit: JZSP-BA02 (battery and connector). Use this battery kit
with cables P/N 004143 and 004149.
6.4.2. Replacing Battery
1. With XtraDrive control power turned ON, replace the old battery
with a new one.
2. Turn OFF the XtraDrive control power to clear the absolute
encoder battery alarm (A.83).
3. Turn ON the XtraDrive control power.
4. Make sure that XtraDrive is operating normally after power is
turned on.
Battery replacement is now completed. After replacing the battery,
initialize the absolute encoder. Refer to XtraDrive Series User's Manual
(Cat No. 8U0108), Initializing of Absolute Encoder.
