(5) Troubleshooting
CAUTION
Use a motor with electromagnetic brakes or
establish an external brake mechanism for
the purpose of holding; this serves as
countermeasures for possible hazardous
situation caused by power failure or
product fault.
Use a double circuit structure for the
electromagnetic brake
’
s operation circuit
so that the brakes will activate even when
the external emergency stop signal is
issued.
The machine could suddenly restart when the power is restored after an instantaneous power failure, so
stay away from the machine. (Design the machine so that the operator safety can be ensured even if the
machine restarts.)
To secure the absolute position, do not shut off the servo drive unit
’
s control power supply when its
battery voltage drops (warning 9F) in the servo drive unit side.
If the battery voltage drop warning alarm occurs in the controller side, make sure to back up the machining
programs, tool data and parameters, etc. with the input/output device before replacing the battery.
Depending on the level of voltage drop, memory loss could have happened. In that case, reload all the data
backed up before the alarm occurrence.
