(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
position board 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 position board, always touch grounded metal, etc. to discharge static
electricity from human body. Failure to do so may cause the position board to fail or malfunction.
Do not directly touch the position board's conductive parts and electronic components.
Touching them could cause an operation failure or give damage to the position board.
Do not place the position board 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 position board or servo amplifier, always set the new position board
settings correctly.
When the position board or absolute value motor has been replaced, carry out a home position
return operation from the user program. Failing to do so may cause position displacement.
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
position board 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 position board and servo amplifier. Doing so may cause a toxic gas.
