Operation
Maintenance and Inspection
Disposal
• Follow the procedures and instructions in the user’s manuals for the relevant Machine Control-
lers to perform normal operation and trial operation.
Operating mistakes while the Servomotor and machine are connected may damage the machine or even
cause accidents resulting in injury or death.
• Implement interlock signals and other safety circuits external to the Machine Controller to
ensure safety in the overall system even if the following conditions occur.
• Machine Controller failure or errors caused by external factors
• Shutdown of operation due to Machine Controller detection of an error in self-diagnosis and the subse-
quent turning OFF or holding of output signals
• Holding of the ON or OFF status of outputs from the Machine Controller due to fusing or burning of out-
put relays or damage to output transistors
• Voltage drops from overloads or short-circuits in the 24-V output from the Machine Controller and the
subsequent inability to output signals
• Unexpected outputs due to errors in the power supply, I/O, or memory that cannot be detected by the
Machine Controller through self-diagnosis.
There is a risk of injury, device damage, or burning.
• Do not attempt to disassemble or repair the Machine Controller.
There is a risk of electrical shock, injury, or device damage.
• Do not change any wiring while power is being supplied.
There is a risk of electrical shock, injury, or device damage.
• Suitable battery replacement must be performed and it must be performed only by an experi-
enced technician.
There is a risk of electrical shock, injury, or device damage.
• Do not forget to perform the following tasks when you replace the CPU Unit/CPU Module:
• Back up all programs and parameters from the CPU Unit/CPU Module that is being replaced.
• Transfer all saved programs and parameters to the new CPU Unit/CPU Module.
If you operate the CPU Unit/CPU Module without transferring this data, unexpected operation may
occur. There is a risk of injury or device damage.
• Do not touch the heat sink on the CPU Unit/CPU Module while the power supply is turned ON
or for a sufficient period of time after the power supply is turned OFF.
The heat sink may be very hot, and there is a risk of burn injury.
• Dispose of the Machine Controller as general industrial waste.
• Observe all local laws and ordinances when you dispose of used Batteries.
