(MR-J3BAT)
Battery connection relay cable
(MR-J3BTCBL03M)
Use this to hold the absolute value when shipping the product with the machine and servo amplifier removed. The servo motor HF
series does not have a super capacitor (for holding absolute value for short time) in the encoder. When this option cable is used,
the absolute value can be held even when the encoder cable is disconnected from the servo amplifier, making it easy to do
maintenance on the servo amplifier.
The servo motor’s absolute value can be maintained by installing a battery in the servo amplifier.
There is no need to install the battery when your servo system is used in an incremental mode.

● Diagnostic cable (MR-J3ACHECK)
This cable is required to use the amplifier diagnostic
function MR Configurator (Setup software).
● Battery connection relay cable (MR-J3BTCBL03M)

Note: The 44th Edition of the IATA (International Air Transportation Association) Dangerous Goods Regulations was effected in
January 1st, 2003 and administered immediately.
In this edition, the provisions relating to lithium and lithium ion batteries have been revised to strengthen regulations on the
air transportation of battery.
This battery is not dangerous goods (not class 9). Therefore, these batteries of 24 units or less are not subject to the regulations.
These batteries more than 24 units require packing based on Packing Instruction 903.
If you need the self-certification form for the battery safety test, contact Mitsubishi.
For more information, contact Mitsubishi. (as of March, 2004)
Notes: 1. The absolute value can not be held when the connections between each cable or the connection with the motor is
disconnected.
2. The encoder cable lead-out direction is shown for the motor shaft side.
An option cable is also available for leading the cable out in the opposite direction of the motor shaft. Refer to the section
“Options ● Cables and Connectors” in this catalog.
