robot controller so that it will always work safely.
•The robot controller has an emergency stop terminal to trigger emergency stop.
Using this terminal, prepare a physical interlock circuit so that the system
including the robot controller will work safely.
cCAUTION
•Do not bundle control lines or communication cables together or in close contact with the
robot controller main circuit or power lines. As a general rule, separate them by at least
100mm. Noise in the main circuit or power lines may cause faulty operation or malfunctions.
•Data (programs, point data, etc.) stored in the robot controller is not guaranteed to be
unchanged, so be sure to back it up onto an external storage device.
[Installation safety points]
wWARNING
•Securely install the connectors into the robot controller, and when wiring the
connectors, make the crimp, press-contact or solder connections correctly using
the tool specified by the manufacturer.
•Always shut off all phases of the power supply externally before starting
installation or wiring work. Failure to shut off all phases could lead to electrical
shocks or product damage.
cCAUTION
•Use the robot controller within the environment specifications listed in this manual.
Using the controller in an environment outside the specification range could lead to electrical
shocks, fires, malfunctions, product damage or lower performance.
•Tighten the screws on the robot controller firmly to make secure connections.
•Never directly touch the conductive sections or electronic components other than the rotary
switches and DIP switches on the outside panel of the robot controller.
•Securely attach each connector cable connector into the receptacles or sockets. Poor
connections will cause faulty operation or malfunctions.
[Wiring safety points]
wWARNING
•Always shut off all phases of the power supply externally before starting
installation or wiring work. Failure to shut off all phases could lead to electrical
shocks or product damage.
•Always attach the terminal cover (supplied) before turning on the power to the
robot controller after installation and wiring work are complete. Failure to attach
the terminal cover could lead to fire, electrical shock, product damage or
malfunctions.
cCAUTION
•Tighten the terminal screws within the specified torque ranges. A loose terminal screw could
lead to short-circuit, faulty operation or malfunctions. However, if the terminal screw is too
tight, short-circuit, faulty operation or malfunctions could also occur due to screw damage.
•Make sure that no foreign matter such as cutting chips or wire scraps do not enter the robot
controller.
•Always store the cables connected to the robot controller in a conduit or clamp them securely
in place. If the cables are not stored in a conduit or properly clamped, excessive play or
movement or mistakenly pulling on the cable might damage the connector or cables, and poor
cable contact may lead to faulty operation or malfunctions.
•When disconnecting the cable, detach by gripping the connector itself and not by tugging on
the cable. Loosen the screws on the connector (if fastened with the screws), and then
disconnect the cable. Detaching by pulling on the cable itself may damage the connector or
cables, and poor cable contact may lead to faulty operation or malfunctions.

[Start-up and maintenance safety points]
wWARNING
•Only personnel trained in safety and robot operation may operate it.
•Never allow anyone to enter the robot movement range when the robot controller
is turned on. Serious accidents including fatal injury or death might otherwise
result.
•This robot controller is not designed to be explosion-proof. Do not use it in
locations exposed to inflammable gases, gasoline or solvent that could cause
explosion or fire.
•Do not touch any electrical terminal while power is supplied to the robot
controller. This might cause electrical shocks, faulty operation or malfunctions.
•Always shut off all phases of the power supply externally before cleaning or
tightening the terminal screws. Failure to shut off all phases could lead to
electrical shocks, product damage or malfunctions. A loose screw could lead to
parts dropping out, short circuits or malfunctions. If the screw is too tight, short
circuits or malfunctions could also occur due to screw damage.
•Never disassemble or modify the robot controller. This may lead to breakdowns,
malfunctions, injury or fire.
•Always shut off all phases of the power supply externally before installing or
removing an option board. Failure to shut off all phases could lead to breakdowns
or malfunctions.
•When using ferrite cores for noise elimination, fit them to the power cable as close
to the robot controller as possible to prevent faulty operation or malfunctions due
to noise.
•When performing maintenance of the robot controller under instructions from the
YAMAHA or YAMAHA sales dealer, turn off the robot controller and wait for at least
30 minutes. Some components in the robot controller may be hot or still retain a
high voltage shortly after operation, so burns or electrical shocks may occur if
those parts are touched.

Before using the robot controller
(Be sure to read the following notes.)
Please be sure to perform the following tasks before using the robot controller.
Failing to perform these tasks will require absolute reset for setting the origin position
each time the power is turned on or may cause abnormal operation (vibration, noise).
[1] When connecting the power supply to the robot controller
Always make a secure connection to the ground terminal on the robot controller to
ensure safety and prevent malfunctions due to noise.
[2] When connecting the battery cable to the robot controller
The absolute battery is fully charged when the robot controller is shipped to the
customer. However, it is left disconnected to prevent battery discharge.After installing
the controller, always be sure to connect the absolute battery while referring to “9.
Connecting the absolute battery” in Chapter 3 before connecting the robot cables.
An error (relating to absolute settings) is always issued if the robot controller power is
turned on without connecting the absolute batteries, so the origin position cannot be
detected. This means the robot connected to this controller cannot be used with absolute
specifications.
[3] When connecting robot cables to the robot controller
Be sure to keep robot cables separate from the robot controller power connection
lines and other equipment power lines. Using in close contact with lines carrying
power may cause malfunctions or abnormal operation.
Reference
Absolute reset is always required when
the robot controller power is first
turned on after connecting the robot
cable to the robot controller. Perform
absolute reset while referring to “11.8
Absolute reset” in Chapter 4,
“Operation”.
Absolute reset is also required after the
robot cable was disconnected from the
robot controller and then reconnected.
Reference
Refer to “4. Connecting to the power”
in Chapter 3, “Installation”.

Overview of the RCX series
The YAMAHA RCX series robot controllers were developed based on years of
YAMAHA experience and proven achievements in robotics and electronics. These
controllers are specifically designed to operate YAMAHA industrial robots efficiently
and accurately.
Despite their compact size, the RCX series controllers operate efficiently as multi-axis
controllers with a variety of functions.
Major features and functions are:
1. Multi-task function
Up to 8 tasks* can be run simultaneously in a specified priority. (Low priority tasks
are halted while high priority tasks are run.)
I/O parallel processing and interrupt processing are also available, so that operational
efficiency of the total robot system including peripheral units is greatly improved.
(*: Refer to the programming manual for more details on multi-tasking.)
2. Robot language
The RCX series controller comes with a BASIC-like high-level robot language that
conforms to the industrial robot programming language SLIM*1. This robot language
allows easy programming even of complex movements such as multi-task operations
and uses a compiling method*2 for rapid execution of programs.
(*1: Standard Language for Industrial Manipulators)
(*2: This compiling method checks the syntax in a robot language program, converts
it into intermediate codes, and creates an execution file (object file) before actually
performing the program.)
3. Movement command
• Arch motion
Spatial movement during pick-and-place work can be freely set according to the
work environment. This is effective in reducing cycle time.
• Three-dimensional CP control
Allows three-dimensional interpolation control of linear and circular movements.
4. Maintenance
Software servo control provides unit standardization. This allows connection to most
YAMAHA robot models and simplifies maintenance.
5. CE marking*
As aYAMAHA robot series product, the RCX series robot controller is designed to
conform to machinery directives, low-voltage directives and EMC (Electromagnetic
compatibility) directives. In this case, the robot controller is set to operate under SAFE
mode. (* For CE marking compatibility, see the CE marking supplement manual.)
This manual explains how to handle and operate theYAMAHA robot controllers correctly
and effectively, as well as I/O interface connections.
Read this manual carefully before installing and using the robot controller. Also refer to
the separate “Programming Manual” and “Robot User's Manual” as needed.

Please observe all safety rules and cautions to ensure safe and correct use of the YAMAHA robot.
Also, bear in mind that not all safety items can be listed in detail, so that accurate judgment by the
operator or service personnel is essential for operating the robot and controller safely.
Industrial robots are highly programmable, mechanical devices that provide a large degree
of freedom for performing various manipulative tasks. To ensure safe and correct of
YAMAHA industrial robots, carefully read this manual and FOLLOWTHEWARNINGS,
CAUTIONS AND INSTRUCTIONS in this chapter. Failure to take necessary safety
measures or mishandling may result in trouble or damage to the robot and injury to
personnel (robot operator or service personnel) including fatal accidents.
Particularly important safety items and operation points are identified in this manual by
the following symbols and signal words.
wWARNING
"WARNING" indicates a potentially hazardous situation which, if not avoided, could
result in death or serious injury.
cCAUTION
"CAUTION" indicates a potentially hazardous situation which, if not avoided, could result in

1. Safety
1.1 Safety precautions during robot operation
a. The robot must be operated by a person who has received the proper training on safety
and operation fromYAMAHA or an authorizedYAMAHA sales dealer.
b. During operation of the robot, be sure to stay out of the work area of the robot
manipulator. Install a safeguard enclosure to keep others away from the work area or
providea gateinterlock using an area sensorthat triggers emergency stop when someone
enters the work area.
c. This robot controller is not designed to be explosion-proof. Do not use the controller
and robot in locations exposed to inflammable gases, gasoline or solvent that could
cause explosion or fire.
1.2 Safety precautions during maintenance
a. Never disassemble the robot or controller. In cases where you have to replace or repair
parts used in the robot or controller, first consult with us and then follow the instructions
we provide.
b. Before beginning maintenance for the robot or controller, be sure to turn off the power
to the controller. Even after turning off the controller, there are some parts in the
controller which are still hot or at a high voltage.Always wait for at least 30 minutes
after the controller is turned off.
1.3 Motor overload precautions
Since abnormal operation (such as overload) of the motor is detected by software, the
controller parameters must be set correctly to match the motor type used in the robot
connected to the controller.
Prior to shipping, the controller parameters are preset to match the robot model to be
used. However, please check the robot model again when connecting it to the controller.
If any abnormality is found during operation, stop the controller and contact us for
corrective action.
