1.3 Handling methods for alarms/warnings

[AL. 092_Battery cable disconnection warning]

• The battery voltage for the absolute position detection system has decreased.

[AL. 092.1_Encoder battery cable disconnection warning]

[AL. 092.3_Battery degradation]

Cause

Check/action method

Model

The battery may not be connected to the servo
amplifier.

Check if the battery is connected correctly.

[JET-G]

The battery cable may have been
disconnected.

Check if the battery cable has malfunctioned.

The battery voltage is too low. The battery is
exhausted.

Check the battery voltage with a tester. If the voltage is lower than 3.1 V DC,
replace the battery.

There is a problem with the encoder cable.

Check if the BAT wiring of the encoder cable has been disconnected or has
shorted.

The servo amplifier has malfunctioned.

Replace the servo amplifier, then check the repeatability.

The encoder has malfunctioned.

Replace the servo motor, then check the repeatability.

Cause

Check/action method

Model

The battery voltage is too low. The battery is
exhausted.

Check the battery voltage with a tester. If the voltage is lower than 3.0 V DC,
replace the battery.

[JET-G]

The battery has malfunctioned.

Replace the battery, then check the repeatability.
