Inspection procedures
Inspect the flexible cables, reduction
gears, ball screw splines, timing belts and
motors, then replace them when
necessary.
Replace the RAM (controller) backup
battery.
If the running time is long, battery
consumption is small. If the power OFF
time is long, the consumption is large. If
the battery voltage drops, the battery
alarm message saying "1–145 MAIN
Battery alarm" is displayed. Then
replace the battery immediately.
As the switching power supply unit uses
an aluminum electrolytic condenser, its
life is limited. Replace the switching
power supply unit (DC5 V, DC24 V) for
preventive maintenance. The life of the
switching power supply unit differs with
load current, running hours and ambient
temperature. If the load current is large,
the running time is long or the ambient
temperature is high, the life becomes
short.
