Absolute
Encoder
Backup Circuits
1) Rotation data for absolute encoder application is backed up during power interruptions by the
absolute encoder backup circuits.
2) Backup Power Supplies
a) Using SGDA, SGDB, SGD, or DR2
(1) Battery Module (Model No.: JRMSP-120XCP96000)
D
Rotation data for up to 8 absolute encoders can be backed up with one Battery Module.
D
The battery backup time without power supply when 8 absolute encoders are connected
is one year, but this time will be shortened if the encoders are operated when power is
not being supplied.
(2) Large-Capacity Capacitor in Absolute Encoder
D
Maximum backup time of 3 days on full charge.
b) Using SGDM or SGDH
(1) Connect a Battery Module to the MC15 Module, or add a lithium backup battery to the SER-
VOPACK.
D
Battery Module (Model No.: JRMSP-120XCP96000) explanation is the same as 2) a) (1)
above.
(2) SERVOPACK Lithium Battery
D
Lithium Battery Model No.: JZSP-BA01 (with battery and connector).
Battery Model: Toshiba ER3V, 3.6 V, 1000 mA h
Refer to the SERVOPACK (SGDM, SGDH) User’s Manual for battery handling
instructions.
3) 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
A 24-VDC, 1-A or 5-VDC, 1-A external power supply is required as power for the external I/O
signals.
WARNING
If using an SGDM or SGDH SERVOPACK, use one of the following as the backup power
supply for the absolute encoder rotation data.
• Connect a Battery Module to the MC15 Module.
• Connect a lithium battery to the SERVOPACK.
Do not use both of the backup methods; there is a risk that unwanted current will flow
between the batteries, resulting in a short-circuit or damage to the element.
