[Appendix 1] Summary of MR-J4_B_-RJ020 + MR-J4-T20
Appendix 1-21
(2) Startup in the absolute position detection system
[AL. 25 Absolute position erased] occurs when switching the power on for the first time, but that is not a
malfunction. When an alarm occurs, the alarm can be canceled by shutting off the power after leaving
the power on for a few minutes with the alarm being issued. If power is switched on with the servo motor
operated at the speed of 500 r/min or higher, position mismatch may occur due to external force. Power
must therefore be switched on when the servo motor is stopped.
POINT
There are two kinds of batteries to use when configuring absolute position
detection system: one is the MR-BAT6V1SET battery and the other is the MR-
BAT6V1BJ battery for battery extension cable. When using the MR-BAT6V1BJ
battery for battery extension cable, it has the following features compared to the
MR-BAT6V1SET battery.
• The encoder cable can be removed from the servo amplifier.
• The battery can be replaced with the control circuit power supply turned off.
When the encoder loses the absolute position data, make sure to operate after
setting the home position. The encoder loses the absolute position data in the
following cases. It may also lose the absolute position data when the battery is
used outside the specified range.
When the MR-BAT6V1SET battery is used
• Removed the encoder cable.
• Replaced the battery with the control circuit power switched off.
When the battery for the MR-BAT6V1BJ battery extension cable is used
• Removed the connector and the cable between the servo motor and the
battery.
The battery for the MR-BAT6V1BJ battery extension cable only supports the HG
series servo motor.
The connector for the SSCNET cable connection cannot supply power to the
encoder. When using with the absolute position sensor detection system, make
sure to connect the battery to the CN4 connector of the servo amplifier.
(3) MR-BAT6V1SET battery specifications
Refer to the following table for items that differ from when using an HG series servo motor.
