1 Function Overview
1.1 Preface
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.
NOTE
1.2
Refer to section 10 for the restrictions.
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
configuration:
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 section
2.1.2 “Signal Distribution Board” on 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 section 3.7 “Starting Safety Range
Function for Robot” on 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)
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.
(5) Logical verification of safety signals
This function detects the unmatch of the dual safety signals
converted into the functional safety unit.

Setup (Safety Range Function for Each Axis)
4.1
Preparation for Safety Range Function
For the safety range function for each axis, set the movement amount of
each axis of the robot in advance. Then, each axis is monitored so that it
does not exceed the safety range.
If any monitoring error is detected, the servo power will be turned OFF.
The outline of the operating procedure is as follows:
(1) Setting expected stop value

(2) Setting safety range for each axis

(3) Confirming safety range for each axis

(4) Starting safety range function for each axis
Each operating procedure is explained below.
4.2
Setting Expected Stop Value
When the servo power is turned OFF during robot operation, the robot
keeps moving due to inertia until it stops completely. The functional safety
unit predicts the movement distance (hereinafter called the coasting
value) according to the speed of each axis until the robot actually stops.
By predicting the coasting value, the robot does not exceed the safety
range even if an error, such as the robot’s exceeding the safety range, is
detected.
For example, when the robot is operating at 100% of its motion speed, the
functional safety unit starts to stop it from “the distance of the coasting
value of 100% motion speed”. When the robot is operating at 50% of its
motion speed, the functional safety unit starts to stop it from “the distance
of the coasting value of 50% motion speed”.
To perform the above predictive control, the robot may stop before the
safety range when it moves to the teaching point near the safety range.
To add an teaching point near the safety range, take the following
measures:
(1) Lower the teaching speed
(2) Change the teaching point
(3) Change the setting of the safety range to widen it
Regarding the coasting value of the external axis, settings must be made
by the user as instructed in the following.
If settings of the coasting value are not completed, the following error
occurs and playback cannot be performed.
Error 0384: “Coasting value setting of Ex-axis is not completed.”

Stop Position Monitoring Function
5.1
Operating Condition Detection
The stop position monitoring function is one of the functions of the
functional safety unit. With this function, the encoder information of the
robot or external axis is monitored. If the robot or external axis moves
when the function is valid, the power supply to the servo is shut off
immediately to turn the servo power OFF.
The VALID/INVALID setting of the stop position monitoring function is
performed by the turning ON/OFF of the external dual signal (e.g. area
sensor, mat switch).
When using this function, refer to section 5.2 “Turning Stop Position
Monitoring Function VALID/INVALID” and connect the dual signal.
If the movement of each axis is detected, the following alarm occurs and
the servo power is turned OFF.

CAUTION
•
Connect an independent switch (dry contact) for the signal.
If the semiconductor output (*periodic OFF check diagnosis) is
directly connected, the input circuit may malfunction.
The signal must be received by a control device such as a safety
relay unit before connecting the contact signal.
Note that an appropriate control device must be used to achieve the
safety function.
•
The load current of 24 VDC/8.5 mA (typ) flows through each input
circuit.
For the connection, use a switching device capable of switching
24 VDC at 8.5 mA (typ).
•
The dual input signals are checked whether they are synchronized.
Set the dual input signals as the signals which turn ON and OFF
simultaneously. If the dual input signal’s turning ON and OFF are
different in timings with 500 ms or more, the alarm of “INPUT
SIGNAL ERROR” occurs.
•
A screwless terminal block is used as the terminal block 151XT.
See below for the applicable wire and wire termination.
Applicable wire: 0.3 to 1.0 mm dia. (AWG 28 to 18)
