Battery 1 year
Purchase a new battery from our sales office. Replace the old battery
with the new one after purchase by referring to [How to replace the
backup battery].
Electrode
capacitor
5 years
When the capacitor is operated in an environment of 40
℃
in average
temperature throughout the year.
It varies depending on the use environment.
Relay
100,000 times
(Number of power
ON times)
Use the relay at the frequency of turning power ON/OFF of 30
times/day or less.
The life of the cooling fan assumes that this driver is operated 24 hours a day in an environment of 40
℃
in
average temperature throughout the year.
The life of the battery assumes that the driver remains unpowered in a condition connected to the actuator.
Backup battery
The backup battery is used to hold the multi revolution data in the absolute encoder when the power
supply is cut off.
The absolute encoder has a built-in capacitor to hold the data even after the backup battery is
replaced.
All drivers of absolute encoder model come with this battery pre-assembled.
