6 INSPECTION AND MAINTENANCE
6.1 Maintenance Works
6.1.1 Instruction of inspection works
In order that can use the Motion controller in safety and normal, those items that must
be inspected list below.
DANGER
Never open the front case or terminal covers while the power is ON or the unit is running, as this may
lead to electric shocks.
Never run the unit with the front case or terminal cover removed. The high voltage terminal and
charged sections will be exposed and may lead to electric shocks.
Never remove the front case or terminal cover at times other than wiring work or periodic inspections
even if the power is OFF. The insides of the Motion controller and servo amplifier are charged and
may lead to electric shocks.
When performing wiring work or inspections, turn the power OFF, wait at least ten minutes, and then
check the voltage with a tester, etc. Failing to do so may lead to electric shocks.
Never operate the switches with wet hands, as this may lead to electric shocks.
Do not damage, apply excessive stress, place heavy things on or sandwich the cables, as this may
lead to electric shocks or fire.
Do not touch the Motion controller, servo amplifier or servomotor terminal blocks while the power is
ON, as this may lead to electric shocks or fire.
Do not touch the built-in power supply, built-in grounding or signal wires of the Motion controller and
servo amplifier, as this may lead to electric shocks.
CAUTION
Be sure to ground the Motion controller, servo amplifier and servomotor. Do not ground commonly
with other devices. (Ground resistance : 100
or less)
The wiring work and inspections must be done by a qualified technician.
Wire the units after mounting the Motion controller, servo amplifier and servomotor. Failing to do so
may lead to electric shocks or damage.
Perform the daily and periodic inspections according to the instruction manual.
Perform maintenance and inspection after backing up the program and parameters for the Motion
controller and servo amplifier.
Do not place fingers or hands in the clearance when opening or closing any opening.
Periodically replace consumable parts such as batteries according to the instruction manual.
Do not touch the lead sections such as ICs or the connector contacts.
Do not place the Motion controller or servo amplifier on metal that may cause a power leakage or
wood, plastic or vinyl that may cause static electricity buildup.
Do not perform a megger test (insulation resistance measurement) during inspection.
When replacing the Motion controller or servo amplifier, always set the new unit settings correctly.
After maintenance and inspections are completed, confirm that the position detection of the absolute
position detector function is correct.
