definitions of these terms and related symbols given below, before you proceed to the text itself.
WARNING
CAUTION
Alerts you to those conditions, which could result
in serious bodily injury or death if the instructions
are not followed correctly.
Alerts you to those conditions, which could result
in minor bodily injury or substantial property
damage if the instructions are not followed
correctly.
Terminology and Definitions
Maximum space: Refers to the volume of space encompassing the maximum designed movements of
all robot parts including the end-effector, workpiece and attachments. (Quoted from the RIA*
Committee Draft.)
Restricted space: Refers to the portion of the maximum space to which a robot is restricted by limiting
devices (i.e., mechanical stops). The maximum distance that the robot, end-effector, and workpiece
can travel after the limiting device is actuated defines the boundaries of the restricted space of the
robot. (Quoted from the RIA Committee Draft.)
Motion space: Refers to the portion of the restricted space to which a robot is restricted by software
motion limits. The maximum distance that the robot, end-effector, and workpiece can travel after the
software motion limits are set defines the boundaries of the motion space of the robot. (The "motion
space" is DENSO WAVE-proprietary terminology.)
Operating space: Refers to the portion of the restricted space (or motion space in Denso robot) that is
actually used by the robot while performing its task program. (Quoted from the RIA Committee Draft.)
Task program: Refers to a set of instructions for motion and auxiliary functions that define the specific
intended task of the robot system. (Quoted from the RIA Committee Draft.)

2.1.1 For standard typeThe standard type has not been designed to withstand
explosions, dust-proof, nor is it splash-proof. Therefore, it
should not be installed in any environment where:
(1) there are flammable gases or liquids,
(2) there are any shavings from metal processing or other
conductive material flying about,
(3) there are any acidic, alkaline or other corrosive gases,
(4) there is cutting or grinding oil mist,
(5) it may likely be submerged in fluid,
(6) there is sulfuric cutting or grinding oil mist, or
2.1.2 For dust-proof, splashproof type
(7) there are any large-sized inverters, high output/high
frequency transmitters, large contactors, welders, or other
sources of electrical noise.
The dust-proof, splash-proof type is an IP54-equivalent
structure, but it has not been designed to withstand explosions.
(The HS-E-W and the wrist of the VM-D-W/VS-E-W are an
IP65-equivalent dust-proof and splash-proof structure.)
Note that the robot controller is not a dust- or splash-proof
structure. Therefore, when using the robot controller in an
environment exposed to mist, put it in an optional protective
box.
The dust-proof, splash-proof type should not be installed in any
environment where:
(1) there are any flammable gases or liquids,
(2) there are any acidic, alkaline or other corrosive gases,
(3) there are any large-sized inverters, high output/high
frequency transmitters, large contactors, welders, or other
sources of electrical noise,
(4) it may likely be submerged in fluid,
(5) there are any grinding or machining chips or shavings,
2.2Service space
(6) any machining oil not specified in this manual is in use, or
Note: Yushiron Oil No. 4C (non-soluble) is specified.
(7) there is sulfuric cutting or grinding oil mist.
The robot and peripheral equipment should be installed so that
sufficient service space is maintained for safe teaching,
maintenance, and inspection.

Construct the fence or enclosure so that no one can easily
get past it by climbing over the fence or enclosure.
(4) The fence or enclosure should be constructed to ensure
that it is not possible for hands or any other parts of the
body to get through it.
(5) Take any one of the following protections for the entrance/
exit of the fence or enclosure:
1) Place a door, rope or chain across the entrance/exit of
the fence or enclosure, and fit it with an interlock that
ensures the emergency stop device operates
automatically if it is opened or removed.
2) Post a warning notice at the entrance/exit of the fence
or enclosure stating "In operation--Entry forbidden" or
"Work in progress--Do not operate" and ensure that
workers follow these instructions at all times.
2.9Positioning of rope or
chain
When mak ing a test run, before setting up the fence or
enclosure, place an overseer in a position outside the
robot’s restricted space and one in which he/she can
see all of the robot’s movements. The overseer should
prevent workers from entering the robot's restricted
space and be devoted solely to that task.
If it is not possible to set up the safety fence or enclosure
described in Section 2.8, hang a rope or chain around the
perimeter of the robot’s restricted space to ensure that no one
can enter the restricted space.
(1) Ensure the support posts cannot be moved easily.
(2) Ensure that the rope or chain’s color or material can easily
be discerned from the surrounds.

2.1 Standard Mode and Compatible Mode
The robot controller can be operated in two different modes – standard mode and
compatible mode. The default is standard mode. Select either mode before operating
the robot controller.
In the standard mode, all of the advantages can be expected from the new model of
the robot controller by simultaneously running two or more programs with
multitasking.
The compatible mode focuses on compatibility with conventional DENSO robots. Use
this mode whenever compatibility is required. For example, when replacing a
conventional robot with a new model. However, there are some restrictions on the
use of new functions, such as mu lt itasking, in this mode.

2.3 Types and General Information about I/O Signals
This section describes the I/O signals for the Robot Controller.
The I/O signals are grouped into user I/O signals and system I/O signals.
User I/O signals are compatible with conventional signals, including the pin
pattern, in compat ibl e mode. Note that the connector pin meanings are dif ferent
between standard mode and compatible mode. Some of the signal lines used
for user I/O in compatible mode are used for system input in standard mode.
Additionally, part of the signal lines used for system I/O in compatible mode is
used for command execution I/O signals in standard mode.
2.3.1 Standard Mode
In standard mode, 30 input points for command execution are used to direct
program start and other instructions as I/O commands.
The table below lists the types of I/O signals used in standard mode.
Ty pes of System I/O Signals Used in Standard Mode
Robot initialization complete, automatic operation mode, external mode,
servo ON, robot-in-operation, normal CPU, robot failure, robot warning,

23
2.4 Using User I/O Signals (common to both modes)
To use user I/O signals you need to first declare, in the program, the use of u ser I/O
as I/O type variables with a DEFIO command. Next, access the user I/O by writing it
to the I/O type variables or reading it.
2.4.1 I/O T ype Variable Declaration
I/O type variables are classified into I/O type global variables that are available
without any declaration, and I/O type local variables that are not available without a
declaration.
2.4.2 I/O T ype Global Variables
I/O type global variables are used to refer to or change user I/O signals bit by bi t.
Since they are global variab les, they can be used without any declaration.
I/O type global variables are expressed in either of the following two ways:
IO[nn](nn: terminal number)Example: IO[104]
IOnn (nn: terminal number)Example: IO104
2.4.3 I/O Type Local Variables
I/O type local variables are used to collectively refer to or change 1-bit, 8-bit, 16-bit or
32-bit user I/O signals starting from a specified terminal number.
I/O type local variables require a declaration, which will be made with a DEFIO
command, before they are used. For further information about declarations with a
DEFIO command, refer to the PROGRAMMER'S MANUAL (I), Chapter 9, Section
9.7 "DEFIO (Statement) [Conforms to SLIM]."
2.4.4 User Input Commands
There are two types of user input commands, IN and WAIT. The IN command
substitutes the input result for a variable. The WAIT command waits until the input
result meets specified conditions.
•IN Command
The IN command inputs a signal from the user input specified by an IO type variable
and substitutes it for an arith meti c variable.
For further information about the IN command, refer to the PROGRAMMER'S
MANUAL (I), Chapter 13, Sect ion 13.1 "IN."
•WAIT Command
The WAIT command suspends the execution of the program until specified
conditions are met. If an I/O type variable is u sed for the condition al statement, this
command suspends the execution of the program until the status of the signal from a
specified user input is checked and meets the specified conditions. For further
information about the WAIT command, refer to the PROGRAMMER'S MANUAL (I),
Chapter 12, Section 12.5 "WAIT."
24
2.4.5 User Output Commands
There are three types of user output commands, SET, RESET and OUT. The SET
and RESET commands turn ON and OFF all user outputs specified by I/O type
variables. The OUT co mma nd outputs data to a specified user output.
•SET Command
The SET command turns ON all user outputs specified by I/O type variables.
For further information about the SET command, refer to the PROGRAMMER'S
MANUAL (I), Chapter 13, Section 13.1 "SET."
•RESET Command
The RESET command turns OFF all user outputs specified by I/O type variables.
For further information about the RESET command, refer to the PROGRAMMER'S
MANUAL (I), Chapter 13, Section 13.1 "RESET ."
•OUT Command
The OUT command outputs data to the user output specified by an I/O type variable.
For further information about the OUT command, refer to the PROGRAMMER'S
MANUAL (I), Chapter 13, Section 13.1 "OUT."

The controller starts processing based on the command it read.
If the command is one that outputs a status, the controller sets the status
area and status parity.
After command processing has been completed and a status area has
been set, the controller turns ON the command processing complete
signal.
If an error occurs in the while processing, a robot failure signal will be
outputted together with the command processing complete signal.
The PLC waits until the command processing complete signal is input, and
receives the status of the status area, if necessary. In this case,
confirmation that no error exists with the robot.
After the PLC has read the status, it turns OFF the command and data
areas and the strobe signal.
As soon as the strobe signal is turned OFF, the controller turns OFF the
status area and the command processing complete signal.
The robot failure signal, which is outputted due to a command processing
error, rema ins ON until a CLEAR ROBOT FAILURE command is executed.
Caution: SSSS The maximum time taken until the status area and the
command processing complete signal are turned OFF, after
the strobe signal is turned OFF in XXXX, is 100 msec.
