2 SYSTEM CONFIGURATION
(2) Data back-up of Motion controller by the battery
Be sure to set the battery to the Motion controller.
Set the battery (Q6BAT/Q7BAT) to battery holder.
The data (Refer to Section 6.5.) of RAM built-in Motion controller are backed up
without using the battery.
In the following status, the backup time after power OFF is 3 minutes.
• The Q6BAT/Q7BAT lead connector is disconnected.
• The lead wire of Q6BAT/Q7BAT is broken.

(Note-1) : The actual service value indicates the average value, and the guaranteed value indicates the minimum value.
(Note-2) : The power-on time ratio indicates the ratio of Motion controller power-on time to one day (24 hours).
(When the total power-on time is 17 hours and the total power-off time is 7 hours, the power-on time ratio is 70%.)
(Note-3) : The guaranteed value (MIN) ; equivalent to the total power failure time that is calculated based on the characteristics value of
the memory (SRAM) supplied by the manufacturer and under the storage ambient temperature range of -25°C to 75°C (-13 to
167°F) (operating ambient temperature of 0°C to 55°C (32 to 131°F)).
(Note-4) : The guaranteed value (TYP) ; equivalent to the total power failure time that is calculated based on the normal air-conditioned
environment (40°C (104°F)).
(Note-5) : The actual service value (Reference value) ; equivalent to the total power failure time that is calculated based on the measured
value and under the storage ambient temperature of 25°C (77°F). This value is intended for reference only, as it varies with
characteristics of the memory.
POINTS
The self-discharge influences the life of battery without the connection to Motion
controller. The battery should be exchanged approximately every 4 or 5 years.
And, exchange the battery with a new one in 4 to 5 years even if a total power
failure time is guaranteed value or less.
