Maximum revolution range
(Note 1) Maximum speed at power failure
(Note 2) Battery backup time
(Note 3) Data holding time during battery
replacement
Battery storage period
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. It is recommended to replace the battery in three years independently of
whether power is kept on or 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.
(2) Configuration
Servo system controller
(3) Parameter setting
Set "0001" in parameter No.1 to make the absolute position detection system valid.
