Installation Guide

D

CAUTION

This product is only for MR J4 servo amplifiers. This is not available with other servo

amplifiers.

To avoid deleting data, replace an MR-BAT6V1BJ according to procedures written in this

installation guide.

This product is compatible only with HG series servo motors.

When replacing an MR-BAT6V1BJ, use new one.

Check that the new MR-BAT6V1BJ is within its estimated life.

The battery built in MR-BAT6V1BJ cannot be replaced. Do not disassemble the MR-

BAT6V1BJ. Otherwise, it may cause a malfunction.

1. INTRODUCTION

This product is only for MR J4 servo amplifiers. This is not available with other servo amplifiers.

Using MR-BAT6V1BJ battery for junction battery cable enables you to keep the absolute position data recorded in

the encoder even if the servo amplifier is removed from machine.

2. SPECIFICATIONS

Item Description

Note. Quality of the batteries degrades by the storage condition. The battery life is 5 years from the production date regardless of the

connection status.

Production year and month are indicated in a serial number (SERIAL) on the rating plate. The second digit from left in the number

indicates the first digit of the year, The third digit from left indicates a month (Oct: X, Nov: Y, Dec.: Z). For November 2013, the serial

is like, "SERIAL: _ 3Y _ _ _ _ _ _".

4. Configuration

4.1 Mounting

(1) Wire the product using the MR-BT6VCBL03M junction battery cable as follows.

(2) After wiring, startup the absolute position detection system. Even if the connector for branch cable

connection (black) is not connected to the MR-BT6VCBL03M junction battery cable, an alarm will not occur.

Check that they are connected securely.

(3) When you transport a servo amplifier and machine apart, disconnect only CN2 and CN4 of the servo

amplifier. When other connectors or cables are disconnected, the absolute position data will be deleted.

4.3 Troubleshooting

The following shows warnings and alarms which are triggered with power on of the servo amplifier when the wiring

of the battery for the junction battery cable is incorrect. When you do not solve a problem even after doing the

following actions, refer to troubleshooting of each servo amplifier instruction manual.

Display Name Cause Action

AL. 9F Battery warning 1. MR-BAT6V1BJ is not connected to CN4. Connect MR-BAT6V1BJ to CN4.

2. Battery voltage dropped. Replace MR-BAT6V1BJ.

AL. 92 Battery cable

disconnection

warning

1. Battery voltage dropped. Replace MR-BAT6V1BJ.

2. MR-BAT6V1BJ is not connected to CN4 or

MR-BT6VCBL03M.

Connect MR-BAT6V1BJ to CN4 and MR-

BT6VCBL03M.

AL. 25 Absolute position

erased

1. The power was turned off while MR-

BAT6V1BJ was not connected to CN4 or

MR-BT6VCBL03M.

Connect MR-BAT6V1BJ to CN4 and MR-

BT6VCBL03M.

2. The servo amplifier was removed from

machine while MR-BAT6V1BJ was not

connected to MR-BT6VCBL03M.

Connect MR-BAT6V1BJ to MR-

BT6VCBL03M.

3. MR-BT6VCBL03M was not connected to

an encoder cable.

Connect the MR-BT6VCBL03M to the

encoder cable.

4.4 Precautions for using

(1) The connector for servo amplifier connection (orange) has a lock release lever. When removing the

connector, pull out the connector while pressing the lock release lever.

(2) The connector servo amplifier connection (orange) and the connector for branch cable connection (black)

are different in color and shape due to different output voltage. Incorrect connection can cause the machine

to be damaged.

(3) When a cable is cut or shorted due to load or being caught, the built-in battery will have high temperature.

Do not disassemble the MR-BAT6V1BJ to prevent getting burnt.

6. Battery transportation

When only lithium metal batteries are transported, attachment of a handling label to each package, submission of

the Shipper's Declaration for Dangerous Goods, and a 1.2 m drop test will be required. When the batteries are

transported with mounted on products, the regulations about package, etc. will not be required.
