Description

System

Electronic battery backup system

Battery

1 piece of lithium battery ( primary battery, nominal 3.6V)

Type: MR-BAT or A6BAT

 

Maximum revolution range

Home position

 

32767 rev.

 

(Note 1) Maximum speed at power failure

500r/min

(Note 2) Battery backup time

Approx. 10,000 hours (battery life with power off)

(Note 3) Data holding time during battery

2 hours at delivery, 1 hour in 5 years after delivery

replacement

 

 

 

Battery storage period

5 years from date of manufacture

Note: 1. Maximum speed available when the shaft is rotated by external force at the time of power failure or the like.

2.Time to hold data by a battery with power off.

3.Period during which data can be held by the super capacitor in the encoder after power-off, with the battery voltage low or the battery removed, or during which data can be held with the encoder cable disconnected.

Battery replacement should be finished within this period.
