SAFETY PRECAUTIONS B-65285EN/03
- Notes on replacing the battery of the absolute pulse coder
Replace the battery only while the power is on. If the battery is
replaced while the power is turned off, the stored absolute
positioning data will be lost. Some series servo amplifier modules
have batteries in their servo amplifiers. To replace the battery of
any of those models, observe the following procedure: Open the
door of the power magnetics cabinet; Leave the control power of
the power supply module on; Place the machine in the emergency
stop state so that the power being input to the amplifier is shut off;
Then, replace the battery. Replacement work should be done only
by a person who is trained in the related maintenance and safety
requirements. The power magnetics cabinet in which the servo
amplifier is mounted has a high-voltage section. This section
presents a severe risk of electric shock.
- Check the number of any alarm.
If the machine stops upon an alarm being issued, check the alarm
number. Some alarms indicate that a component must be replaced.
If the power is reconnected without first replacing the failed
component, another component may be damaged, making it
difficult to locate the original cause of the alarm.
- Before resetting an alarm, ensure that the original cause of
the alarm has been removed.
- Contact FANUC whenever a question relating to
- Notes on removing the amplifier
Before removing the amplifier, first ensure that the power is shut
off. Be careful not to jam your fingers between the power
magnetics cabinet and amplifier.
