7.1 Inspection
The servo amplifier and servomotor are maintenance free and no special daily inspection is
necessary. However, to avoid accidents and operate the devices for a long term at a stable reliability,
perform periodical inspection.
WARNING
After turning the power off, wait for at least five minutes and check that the charge LED is unlit
before performing inspection.
There is a risk of electric shock.
Do not touch the servomotor, servo amplifier and cables in the power-on state.
There is a risk of electric shock.
Never disassemble or remodel the servomotor and servo amplifier.
It might cause fire and failure. It will not be covered by the warranty.
Periodic inspection items
The periodic inspection items are shown below.
Device
Description of inspection
Servomotor
There is no deviation
*1)
in the linkage between the servomotor shaft and
mechanical system.
The servomotor is free from direct splashes of water, vapor or oil.
The servomotor itself does not vibrate excessively.
Servo amplifier
Screws of the terminal block and mounting sections are not loose.
Connectors are inserted correctly.
There is no massive dust on the servo amplifier.
There is no malodor, damage, breakage or faults in appearance.
There should be no characters missing at the keypad display.
The cooling fan should be running.
The fan should not be clogged.
The safety function (STO) should function normally (every 3 months).
*1) Indicates faults in installation such as an angle error, parallelism eccentricity, axial
displacement or similar in the linkage between the servomotor shaft and mechanical system.
Before checking cables of the servomotor and servo amplifier, turn the power off and wait
at least five minutes and check that the charge LED is unlit.
CAUTION
Do not perform a Megger test of the printed circuit board and terminal block.
Otherwise the servo amplifier or the encoder built in the servomotor may be damaged.
