bromine, or iodine) during transportation.
There is a risk of malfunction or damage.
• If disinfectants or insecticides must be used to treat packing materials such as wooden frames,
pallets, or plywood, the packing materials must be treated before the product is packaged, and
methods other than fumigation must be used.
Example: Heat treatment, where materials are kiln-dried to a core temperature of 56°C for 30 minutes or
more.
If the electronic products, which include stand-alone products and products installed in machines, are
packed with fumigated wooden materials, the electrical components may be greatly damaged by the
gases or fumes resulting from the fumigation process. In particular, disinfectants containing halogen,
which includes chlorine, fluorine, bromine, or iodine can contribute to the erosion of the capacitors.
viii

• Provide sufficient shielding when using the Machine Controller in the following locations.
• Locations that are subject to noise, such as from static electricity
• Locations that are subject to strong electromagnetic or magnetic fields
• Locations that are subject to radiation
• Locations that are near power lines
There is a risk of device damage.
• Configure the circuits to turn ON the power supply to the CPU Unit/CPU Module before the 24V I/O power supply. Refer to the following manual for details on circuits.
MP3000 Series CPU Unit Instructions (Manual No.: TOBP C880725 16)
MP3000 Series MP3300 CPU Module Instructions Manual (Manual No.: TOBP C880725 23)
If the power supply to the CPU Unit/CPU Module is turned ON after the external power supply, e.g., the
24-V I/O power supply, the outputs from the CPU Unit/CPU Module may momentarily turn ON when
the power supply to the CPU Unit/CPU Module turns ON. This can result in unexpected operation that
may cause injury or device damage.
• Provide emergency stop circuits, interlock circuits, limit circuits, and any other required safety
measures in control circuits outside of the Machine Controller.
There is a risk of injury or device damage.
• If you use MECHATROLINK I/O Modules, use the establishment of MECHATROLINK communications as an interlock output condition.
There is a risk of device damage.
• Connect the Battery with the correct polarity.
There is a risk of battery damage or explosion.
• Suitable battery replacement must be performed and it must be performed only by an experienced technician.
There is a risk of electrical shock, injury, or device damage.
• Do not touch the electrodes when replacing the Battery.
Static electricity may damage the electrodes.
• Select the I/O signal wires for external wiring to connect the Machine Controller to external
devices based on the following criteria:

the control panel to reduce the influence of noise from the power cables.
If the I/O signal lines and power lines are not separated properly, malfunction may occur.
Operation
CAUTION
CAUTION
• Follow the procedures and instructions in the user’s manuals for the relevant products 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.
• Observe the setting methods that are given in the manual for the following parameters.
• Parameters for absolute position detection when the axis type is set to a finite-length axis
• Parameters for simple absolute infinite-length position control when the axis type is set to an infinite-
length axis
MP3000 Series Motion Control User’s Manual (Manual No. SIEP C880725 11)
If any other methods are used, offset in the current position when the power supply is turned OFF and ON
again may result in device damage.
•OL48 (Zero Point Position Offset in Machine Coordinate System) is always valid when
the axis type is set to a finite-length axis. Do not change the setting of OL48 while the
Machine Controller is operating.
There is a risk of machine damage or an accident.

Example of Basic Path for Positioning (MOV) Instruction
• Always check to confirm the paths of axes when any of the following axis movement instructions are used in programs to ensure that the system operates safely.
• Positioning (MOV)
• Linear Interpolation (MVS)
• Circular Interpolation (MCC or MCW)
• Helical Interpolation (MCC or MCW)
• Set-time Positioning (MVT)
• Linear Interpolation with Skip Function (SKP)
• Zero Point Return (ZRN)
• External Positioning (EXM)
There is a risk of injury or device damage.
• The same coordinate word will create a completely different travel operation in Absolute Mode
and in Incremental Mode. Make sure that the ABS and INC instructions are used correctly
before you start operation.
There is a risk of injury or device damage.
• The travel path for the Positioning (MOV) instructions will not necessarily be a straight line.
Check to confirm the paths of the axis when this instruction is used in programs to ensure that
the system operates safely.
There is a risk of injury or device damage.
• The Linear Interpolation (MVS) instruction can be used on both linear axes and rotary axes.
However, if a rotary axis is included, the linear interpolation path will not necessarily be a
straight line. Check to confirm the paths of the axis when this instruction is used in programs to
ensure that the system operates safely.
There is a risk of injury or device damage.
• The linear interpolation for the Helical Interpolation (MCW and MCC) instructions can be used
for both linear axes and rotary axes. However, depending on how the linear axis is taken, the
path of helical interpolation will not be a helix. Check to confirm the paths of the axis when this
instruction is used in programs to ensure that the system operates safely.
There is a risk of injury or device damage.

• The Set Current Position (POS) Instruction creates a new working coordinate system. Therefore, unexpected operation may occur if the POS instruction is specified incorrectly. When you
use the POS instruction, always confirm that the working coordinate system is in the correct
position before you begin operation.
There is a risk of injury or device damage.
• The Move on Machine Coordinates (MVM) instruction temporarily performs positioning to a
coordinate position in the machine coordinate system. Therefore, unexpected operation may
occur if the instruction is executed without confirming the zero point position in the machine
coordinate system first. When you use the MVM instruction, always confirm that the machine
zero point is in the correct position before you begin operation.
There is a risk of injury or device damage.

CAUTION
CAUTION
Maintenance and Inspection
• 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 experienced technician.
There is a risk of electrical shock, injury, or device damage.
• Replace the Battery only while power is supplied to the Machine Controller.
Replacing the Battery while the power supply to the Machine Controller is turned OFF may result in loss
of the data stored in memory in the Machine Controller.
• When you replace the Battery, do not touch the electrodes of the Battery.
There is a risk of electrostatic discharge failure.
• Do not forget to perform the following tasks when you replace the CPU Unit/CPU Module:
