[Design Precautions]
WARNING
●Configure safety circuits external to the programmable controller to ensure that the entire system
operates safely even when a fault occurs in the external power supply or the programmable controller.
Failure to do so may result in an accident due to an incorrect output or malfunction.
(1) Emergency stop circuits, protection circuits, and protective interlock circuits for conflicting
operations (such as forward/reverse rotations or upper/lower limit positioning) must be configured
external to the programmable controller.
(2) When the programmable controller detects an abnormal condition, it stops the operation and all
outputs are:
• Turned off if the overcurrent or overvoltage protection of the power supply module is activated.
• Held or turned off according to the parameter setting if the self-diagnostic function of the CPU
module detects an error such as a watchdog timer error.
(3) All outputs may be turned on if an error occurs in a part, such as an I/O control part, where the
CPU module cannot detect any error. To ensure safety operation in such a case, provide a safety
mechanism or a fail-safe circuit external to the programmable controller. For a fail-safe circuit
example, refer to "General Safety Requirements" in the MELSEC iQ-R Module Configuration
Manual.
(4) Outputs may remain on or off due to a failure of a component such as a relay and transistor in an
output circuit. Configure an external circuit for monitoring output signals that could cause a
serious accident.
●In an output circuit, when a load current exceeding the rated current or an overcurrent caused by a
load short-circuit flows for a long time, it may cause smoke and fire. To prevent this, configure an
external safety circuit, such as a fuse.
●Configure a circuit so that the programmable controller is turned on first and then the external power
supply. If the external power supply is turned on first, an accident may occur due to an incorrect output
or malfunction.
WARNING
Indicates that incorrect handling may cause hazardous conditions, resulting in
death or severe injury.
CAUTION
Indicates that incorrect handling may cause hazardous conditions, resulting in
minor or moderate injury or property damage.

[Design Precautions]
WARNING
●For the operating status of each station after a communication failure, refer to manuals relevant to the
network. Incorrect output or malfunction due to a communication failure may result in an accident.
●When connecting an external device with a CPU module or intelligent function module to modify data
of a running programmable controller, configure an interlock circuit in the program to ensure that the
entire system will always operate safely. For other forms of control (such as program modification,
parameter change, forced output, or operating status change) of a running programmable controller,
read the relevant manuals carefully and ensure that the operation is safe before proceeding. Improper
operation may damage machines or cause accidents.
●Especially, when a remote programmable controller is controlled by an external device, immediate
action cannot be taken if a problem occurs in the programmable controller due to a communication
failure. To prevent this, configure an interlock circuit in the program, and determine corrective actions
to be taken between the external device and CPU module in case of a communication failure.
●Do not write any data to the "system area" and "write-protect area" of the buffer memory in the
module. Also, do not use any "use prohibited" signals as an output signal from the CPU module to
each module. Doing so may cause malfunction of the programmable controller system. For the
"system area", "write-protect area", and the "use prohibited" signals, refer to the user's manual for the
module used.
●If a communication cable is disconnected, the network may be unstable, resulting in a communication
failure of multiple stations. Configure an interlock circuit in the program to ensure that the entire
system will always operate safely even if communications fail. Failure to do so may result in an
accident due to an incorrect output or malfunction.
●To maintain the safety of the programmable controller system against unauthorized access from
external devices via the network, take appropriate measures. To maintain the safety against
unauthorized access via the Internet, take measures such as installing a firewall.
●Configure safety circuits external to the programmable controller to ensure that the entire system
operates safely even when a fault occurs in the external power supply or the programmable controller.
Failure to do so may result in an accident due to an incorrect output or malfunction.
●If safety standards (ex., robot safety rules, etc.,) apply to the system using the module, servo amplifier
and servo motor, make sure that the safety standards are satisfied.
●Construct a safety circuit externally of the module or servo amplifier if the abnormal operation of the
module or servo amplifier differs from the safety directive operation in the system.
●Do not remove the SSCNET cable while turning on the control circuit power supply of modules and
servo amplifier. Do not see directly the light generated from SSCNET connector of the module or
servo amplifier and the end of SSCNET cable. When the light gets into eyes, you may feel
something wrong with eyes. (The light source of SSCNET complies with class 1 defined in
JISC6802 or IEC60825-1.)

[Design Precautions]
[Installation Precautions]
CAUTION
●Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction
due to noise.
●During control of an inductive load such as a lamp, heater, or solenoid valve, a large current
(approximately ten times greater than normal) may flow when the output is turned from off to on.
Therefore, use a module that has a sufficient current rating.
●After the CPU module is powered on or is reset, the time taken to enter the RUN status varies
depending on the system configuration, parameter settings, and/or program size. Design circuits so
that the entire system will always operate safely, regardless of the time.
●Do not power off the programmable controller or reset the CPU module while the settings are being
written. Doing so will make the data in the flash ROM and SD memory card undefined. The values
need to be set in the buffer memory and written to the flash ROM and SD memory card again. Doing
so also may cause malfunction or failure of the module.
●When changing the operating status of the CPU module from external devices (such as the remote
RUN/STOP functions), select "Do Not Open by Program" for "Opening Method" of "Module
Parameter". If "Open by Program" is selected, an execution of the remote STOP function causes the
communication line to close. Consequently, the CPU module cannot reopen the line, and external
devices cannot execute the remote RUN function.
WARNING
●Shut off the external power supply (all phases) used in the system before mounting or removing the
module. Failure to do so may result in electric shock or cause the module to fail or malfunction.

1.1 Machine Control Overview
• Machine control is the controlling of a simplified robot (link configuration) with a Motion CPU.
• The specified positioning coordinates (X, Y, Z, A, B, C, FL1) are converted by a coordinate transformation machine library
specific to the machine type, which outputs the coordinates to each servo amplifier that makes up the robot.
• Various types of articulated robots can be controlled by installing a machine library (add-on library) that matches the robot
configuration.
• Positioning control
• Motion SFC program
• Coordinate transformation
• 3D interpolation control
• Machine parameter

18 1 OVERVIEW
1.1 Machine Control Overview
• In machine control, parameters for machine control are set and the multiple axes that make up the robot are controlled
together as a machine. A maximum of eight machines can be controlled.
• Machine control uses the machine positioning data set to the devices of the PLC CPU or Motion CPU to start the program
operations of the machine control system. Refer to machine positioning data for the details of machine positioning data.
