6.4 Replacing the Battery
6.4 Replacing the Battery
A battery for memory backup is provided in the controller.
When the battery voltage drops below 2 V, “BAT” will be displayed on the digital operator and the LED indicator “BAT”
on the control board will light up, both indicating low battery voltage. Replace the battery when these alarms have been
tripped.
Yaskawa recommends replacing the battery every 5 years regardless of whether an alarm has been tripped. The battery
replacement interval is indicated on a dedicated nameplate on the controller.
Use battery model CR6L-CN014S.
Note:
Do not turn off the control power with an alarm detected.
Failure to comply may result in loss of the data and the calendar settings stored in the backup memory.
If the control power is turned on when the battery voltage is less than 2 V, the backup data will be automatically cleared.

Battery Replacement Procedure
WARNING!
Electrical Shock Hazard. Do not allow unqualified personnel to perform work on the drive. Failure to comply could result
in serious injury or death. The drive should be installed, wired, repaired, inspected, or serviced, by personnel with a
thorough knowledge of medium-voltage drive installation, adjustment and repair.
NOTICE:
Damage to Equipment. Observe electrostatic discharge procedures (ESD) when handling the drive or circuit boards. Failure
to comply could result in ESD damage to the drive circuitry.
NOTICE:
Damage to Equipment. Do not short-circuit the battery connector when removing or mounting the battery or cleaning the
connector. Failure to comply will result in loss of backup data.
Note:
Replace the battery while the control power is being supplied.
If the control power has been shut off, replace the battery within one hour. The data is backed up by the built-in capacitor for this
time even if there is no battery.
If the control power is off for more than an hour, the backup data may be corrupted. In this case, turn on the control power with
the battery removed to clear the backup data and then set the battery.
Replace the battery by using the following procedure:
1.
Shut off the main circuit power and wait at least 15 minutes.
2.
Remove the cover from the controller.
3.
Remove the battery connector (CN24). The battery alarm LED will light.
Note:
Clean the battery connector with alcohol or equivalent if there is dust or oil on the connector.
4.
Remove the battery from the battery holder.
5.
Mount a new battery in the battery holder. Take care to ensure that the cable is not trapped.
6.
Confirm the polarities and connect the battery
to the connector (CN24).
7.
Check that the battery alarm LED indicator has turned off.
8.
Add the next battery replacement date next to the battery label.
