Battery Backup
1) Memory Backup Circuit
a) Parameter, the motion program, and point table data is maintained by memory
backup circuits during power interruptions.
b) Backup Power Supplies
(1) Lithium Battery in CPU Module
Battery life: 5 yrs (at 25
o
C)
Memory backup time without power supply: 1 yr. (at 25
o
C)
(2) Large-capacity Capacitor in 4-axis Motion Module
Maximum backup time of 3 days on full charge.
2) Absolute Encoder Backup Circuits
a) Rotation data for absolute encoder application is backed up during power
interruptions by the absolute encoder backup circuits.
b) Backup Power Supplies
(1) Battery Module (JRMSP-120XCP96000)
Rotation data for up to 8 absolute encoders can be backed up with one
Battery Module. The memory backup time without power supply when 8
absolute encoders are connected is 1 yr., but this time will be shortened if the
encoders are operated when power is not being supplied.
(2) Large-capacity Capacitor in Absolute Encoder
Maximum backup time of 3 days on full charge.
c) A battery voltage drop detection circuit is built into the Battery Module and an
alarm output for voltage drop can be read with a Digital Input Module.
External Power Supply
The following external power supply is required as power for the external I/O signals:
24 VDC, 2 A
