WARNING
• Before operating the manipulator, check that servo power is turned
OFF pressing the emergency stop buttons on the front door of the
DX100 and the programming pendant.
When the servo power is turned OFF, the SERVO ON LED on the
programming pendant is turned OFF.
Injury or damage to machinery may result if the emergency stop circuit
cannot stop the manipulator during an emergency. The manipulator
should not be used if the emergency stop buttons do not function.
Fig. : Emergency Stop Button
• Once the emergency stop button is released, clear the cell of all
items which could interfere with the operation of the manipulator.
Then turn the servo power ON.
Injury may result from unintentional or unexpected manipulator motion.
Fig. : Release of Emergency Stop
TURN
• Observe the following precautions when performing teaching
operations within the P-point maximum envelope of the
manipulator:
– View the manipulator from the front whenever possible.
– Always follow the predetermined operating procedure.
– Keep in mind the emergency response measures against the
manipulator’s unexpected motion toward you.
– Ensure that you have a safe place to retreat in case of
emergency.
Improper or unintended manipulator operation may result in injury.
• Confirm that no person is present in the P-point maximum envelope
of the manipulator and that you are in a safe location before:
– Turning ON the power for the DX100.
– Moving the manipulator with the programming pendant.
– Running the system in the check mode.
– Performing automatic operations.
Injury may result if anyone enters the P-point maximum envelope of the
manipulator during operation. Always press an emergency stop button
immediately if there is a problem.
The emergency stop buttons are located on the right of front door of the
DX100 and the programming pendant.

1 Function Overview
1.1 Preface
This function limits the operating range of the robot and monitors its
speed.
With this function, the software monitors the robot arm or each axis so that
its position does not exceed the preset safety range. If any monitoring
error is detected, the contactors are cut off to stop the robot. With this
function, it is possible to improve the safety for robot operation, and
reduce the facility space for the robot system.
1.2 Function Overview
(1) Range limit function (robot axis + servo track / unit)
This function is used to monitor the robot so that its position does
not exceed the preset safety range. Only one safety range can be
specified. The specified range can be applied to the following con-
figuration:
Robot (6 axes) + servo track (up to 3 axes)
or
Robot (7 axes) + servo track (up to 2 axes)
By the combination of 2 lines of dual input signals (range switch
signals) to the functional safety unit, 4 ranges (range: 1 to range:
4) can be set as the safety ranges.
To enable range switching, connect the range switch signals to the
functional safety system input terminal block shown in
chapter 2.1.2 “Signal Distribution Board” at page 2-2. When
range switching is not used, i.e. only one safety range is set, there
is no need to connect the signals. (In this case, range: 1 is set.)
For signal connection, refer to chapter 3.7 “Starting Safety Range
Function for Robot” at page 3-15.
(2) Each axis angle limit function (9 axes/unit)
(3) Stop position monitoring function
(4) Safety speed monitoring function
This function monitors the robot to see that it operates at the
safety speed of 250 mm/sec. The speed is monitored at the TCP
(Tool Center Point) and flange.
• Teach mode (manual high speed specification is OFF)
(5) Logical verification of safety signals
This function detects the unmatch of the dual safety signals
converted into the functional safety unit.
NOTE
The safety speed monitoring function can monitor the
speed of one tool number per robot.
The speed of R1 and R2 is monitored using the file with the
tool numbers 0 and 1, respectively.
