Mitsubishi Q172CPU User Manual page 10

If an error occurs, remove the cause, secure the safety and then resume operation after alarm
release.
The unit may suddenly resume operation after a power failure is restored, so do not go near the
machine. (Design the machine so that personal safety can be ensured even if the machine
restarts suddenly.)
(8) Maintenance, inspection and part replacement
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 module settings
correctly.
When the Motion controller or absolute value motor has been replaced, carry out a home
position return operation using one of the following methods, otherwise position displacement
could occur.
1) After writing the servo data to the Motion controller using programming software, switch on
the power again, then perform a home position return operation.
2) Using the backup function of the programming software, load the data backed up before
replacement.
After maintenance and inspections are completed, confirm that the position detection of the
absolute position detector function is correct.
Do not short circuit, charge, overheat, incinerate or disassemble the batteries.
The electrolytic capacitor will generate gas during a fault, so do not place your face near the
Motion controller or servo amplifier.
The electrolytic capacitor and fan will deteriorate. Periodically replace these to prevent
secondary damage from faults. Replacements can be made by our sales representative.
