8.6.2 Replacing battery for motor encoder
■
Battery box attached to the servo amplifier
* If the battery is replaced while the control power is OFF, multiple rotation counter (position data)
of the motor encoder might be instable. When the amplifier control power is turned ON in this
status, an alarm (AL_A1: Absolute Encoder Internal Error 1) might be issued. For this case,
execute encoder clear and alarm reset to release the alarm status. Also, absolute encoder
position data might be instable. So adjust the relations between a position data and a machine
coordinate system to match, and then perform operation.
Process Description
1 Turn ON the servo amplifier control power supply.
