3.5 Replacing the Servo Amplifier Battery

Point

Because XP-Series machines use absolute encoder motors, the encoder data is constantly

stored at the servo amplifier. If this data is lost, the absolute encoder setup procedure

must be repeated, and the Proper data must be re-measured. To prevent the encoder

data from being lost at power off, the servo amplifier is equipped with an internal data

backup battery. This servo amplifier battery must be replaced when a "Servo Amplifier

Error" message displays on the machine's operation screen, with [AL A2] (X-axis) or

[A.830] (All axes other than X) displayed at the 7-segment LED display on the front of the

servo amplifier in question.

Procedure

CAUTION

1. Perform this procedure with the main switch (power

breaker) on.

2. Never remove the battery when the POWER LED is off,

because the absolute position encoder's data will be lost.

1. Verify that the "SYSTEM ON" lamp is on.

2. Press the EMERGENCY STOP button.

3. Locate the servo amplifier that has [AL A2] or [A.830] displayed at its 7-segment

LED display.

4. Replace the battery.

5. Turn the main switch (power breaker) off.

6. Turn the main switch (power breaker) on again, and verify that [AL A2] or [A.830]

is no longer displayed at the servo amplifier.

7. Press the SYSTEM ON button to turn on the power, then verify that the machine

operates normally.

3.6 Replacing the CPU Board Battery

Point

If the SRAM (memory) backup battery on the CPU board fails, then problems such as

lack of trace data will occur. Replace this battery regularly, at 6 year intervals.

Procedure

1. Turn off the power to the machine at the main switch (breaker).

2. Remove the CPU board from the Control Box.

3. Replace the lithium battery (CR2450, commercially available) on the CPU board.

4. Return the CPU to the Control Box.

5. Turn on the machine power and follow the instructions that appear on screen to

resume operation.

CAUTION

• Do not use any battery other than the specified battery.

• Dispose of the used lithium battery in accordance with

your local regulations.
