Absolute System
<Reference>
Following example shows the life calculation of the back-up battery used in assumed robot operation.
2000[mAh] of battery capacity is used for calculation. Note that the following value is not a guaranteed value, but
only represents a calculated value. The values below were calculated with only the current consumption fac-
tored in. The calculations do not factor in electrolyte leakage and other forms of battery deterioration.
Life time may be shortened depending on ambient condition.
1) 2 cycles/day
Annual consumption capacity = (10h x a + 0.0014h x b + 2h x c) x 2 x 313 days + 24h x c x 52 days = 297.8[mAh] )
Battery life = 2000[mAh]/297.8[mAh] = 6.7 (6.7159) [year]
Annual consumption capacity = (10h x a + 0.0014h x b + 14h x c) x 313 days + 24h x c x 52 days = 640.6[mAh] )
Battery life = 2000[mAh]/630.6[mAh] = 3.1 (3.1715) [year]
2) 1 cycle/day
(2nd cycle of the above 1) is for rest.

When you make your own cable for 17-bit absolute encoder
When you make your own cable for 17-bit absolute encoder, connect the optional battery for absolute
encoder, DV0P2060 or DV0P2990 as per the wiring diagram below. Connector of the battery for absolute
encoder shall be provided by customer as well.
<Cautions>
Install and fix the battery securely. If the installation and fixing of the battery is not appropriate, it may cause
the wire breakdown or damage of the battery.
Refer to the instruction manual of the battery for handling the battery.
• Installation Place
1) Indoors, where the products are not subjected to rain or direct sun beam.
2) Where the products are not subjected to corrosive atmospheres such as hydrogen sulfide, sulfurous
acid, chlorine, ammonia, chloric gas, sulfuric gas, acid, alkaline and salt and so on, and are free from
splash of inflammable gas, grinding oil, oil mist, iron powder or chips and etc.
3) Well-ventilated and humid and dust-free place.
4) Vibration-free place
