IS810N-INT Series Servo System User Manual (Brief)Chapter 4 Wiring
Note 1: During normal operation, the absolute encoder supports one-turn or multiturn data
counting and transmitting/receiving. After connecting the absolute encoder properly, turn on
the power to the servo drive, and the encoder enters normal operation state and transmits/
receives data after a delay of 5s. When the encoder switches from standby state to normal
operation state (power turned on), the motor speed must not exceed 10 RPM. Otherwise, the
servo drive reports Er.740, and you need to power on the servo drive again.
Note 2: Standby state: The servo drive is not powered on, and the external battery is used for
multi-turn data counting. In this case, data transmitting/receiving is not performed.
Battery service life:
The calculation below only considers the encoder’s current consumption and does not cover
current consumption of the battery.
Assume that:
Normal operation time of servo drive: T1
Motor rotating time after power-off of servo drive: T2
Motor rotating stop time after power-off: T3 (unit: hour)
Example:
Table 4-10 Theoretical battery service life of an absolute encoder
Item Time Arrangement 1 Time Arrangement 2
Number of days the
battery works under
different working
conditions in 1 year
313 52
T1 (hour) 8 0
T2 (hour) 0.1 0
T3 (hour) 15.9 24
Yearly consumption = (8H x 2uA + 0.1H x 80uA + 15.9H x 10uA) x 313 + (0H x 2uA + 0H x
80uA +24H x 10uA) x 52 ≈ 70 mAH
Theoretical battery service life = Battery capacity/Yearly consumption = 2600 mAH/70 mAH =
37.1 years
