(9) 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
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.
 Before touching the module, always touch grounded metal, etc. to discharge static
electricity from human body. Failure to do so may cause the module to fail or malfunction.
 Do not directly touch the module's conductive parts and electronic components.
Touching them could cause an operation failure or give damage to the module.
 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 drop or impact the battery installed to the module.
Doing so may damage the battery, causing battery liquid to leak in the battery. Do not use
the dropped or impacted battery, but dispose of it.
 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.
 Lock the control panel and prevent access to those who are not certified to handle or
install electric equipment.
 Do not burn or break a module and servo amplifier. Doing so may cause a toxic gas.
