(8) Maintenance, inspection and part replacement
CAUTION
Perform the daily and periodic inspections according to the instruction manual.
Perform maintenance and inspection after backing up the program and parameters for the
control unit 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 control unit 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 control unit or servo amplifier, always set the new unit settings correctly.
When the 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 PC using peripheral device software, switch on the
power again, then perform a home position return operation.
2) Using the backup function of the peripheral device 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
control unit or servo amplifier.
The electrolytic capacitor and fan will deteriorate. Periodically change these to prevent
secondary damage from faults. Replacements can be made by our sales representative.
