6 INSPECTION AND MAINTENANCE
Motion controller Battery type
Q6BAT
Q170MSCPU-S1
(Large capacity)
(Note-1): The battery consumption represents consumption of the Motion controller battery energy.
The larger the battery consumption value is, the more battery per time unit is consumed.
Refer to the "QCPU User's Manual (Hardware Design, Maintenance and Inspection) for details.
(Note-2): The actual service value indicates the average value, and the guaranteed value indicates the minimum value.
(Note-3): 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-4): 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-5): 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-6): 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.
(Note-7): In the following status, the backup time after power OFF is 3 minutes.
• Q6BAT/Q7BAT lead connector is disconnected.
• Lead wire of Q6BAT/Q7BAT is broken.
(Note-8): Battery consumption 1 cannot be used in Q170MSCPU.
(Note-9): Set the battery (Q6BAT/Q7BAT) to battery holder.
