2.2.4 Motion enabling and safe stop
2.2.4.1 Motion enabling
The motion control function of the robot control system should be enabled by the safety
controller, which, when determining the safety level of the current environment through
internal logic, controls on/off of drive STO (Safe Torque Off) via safety output signal.
Manual operation of the robot by the user and automatic running of the program are not
allowed by the control system before the safety controller determines that it is safe at the
moment.
2.2.4.2 Safe stop
There are three ways to stop the robot, i.e. STOP 0, STOP 1 and STOP 2.
Safe stop refers to stop triggered by the safety controller, which only involves STOP 0 and
STOP 1, while STOP 2 can only be triggered by the control system.
STOP 0
As the stop method of the highest safety level, STOP 0 cuts off the power source of the
motors and engages the band-type brakes of individual joints immediately. During the
stopping process, however, the robot is uncontrolled and may deviate from the
programmed path after it is stopped.
Safe stop in manual mode is STOP 0. Safe stop caused by operating mode switchover in
automatic mode is also STOP 0.
STOP 1
Once STOP 1 is triggered, the control system immediately executes the deceleration
process along the programmed path. Thereafter, whether or not the robot comes to a
complete stop, the safety controller will always cut off the power source of the motors and
engage the band-type brakes of all joints. Since the stop is controlled, in most cases, the
robot will finally stop on the programmed path. Therefore, This emergency stop method
provides the best protection for nearby equipment.
Both safe stops arising from the opening of safety gate/safety grating in automatic mode

2 Safety
XB10 Series Product Manual 7
and pressing of the emergency stop button in automatic mode are STOP 1.
STOP 2
Once STOP 2 is triggered, the control system immediately executes deceleration along the
programmed path until the robot stops completely. The power source of the motors is
maintained and the band-type brakes are still disengaged, while the robot stays in the
current position.
2.2.4.3 Emergency stop
As one of the safe stops, emergency stop is the function of the highest priority in the robot
system. Pressing the emergency stop button triggers the emergency stop function. All
other robot control functions will stop, the robot will stop movement, the power source of
the motors of all joints will be cut off, and the control system will switch to the emergency
stop state. Such state will be maintained until reset.
The emergency stop state means that, except the manual band-type brake release circuit,
all other power supplies to the robot arm body will be cut off and the reset operation must
be executed to restore the system to its normal condition.
Tips
Emergency stop is only used to stop the robot immediately in case of danger and
cannot be used as a normal program; otherwise, extra and unnecessary abrasion will
be caused to the band-type brake system and drive system of the robot to reduce the
service life of the robot.
2.2.5 Safety devices
2.2.5.1 Emergency stop button
Most emergency stop buttons are in red. The most common shape is a mushroom. In
general, a yellow substrate, protective casing or warning sign is also attached to the
emergency stop button. The emergency stop button is mechanically locked when it is
pressed. This is the safety lock mechanism for the button. The device must be reset
through manual release. Most emergency stop buttons are released by rotation and the
direction of rotation is indicated on the button surface. Some buttons also support
releasing by upward pulling.
2.2.5.2 Enabling switch
The enabling device is a special switch with two pressing modes and three positions,
which is also called three-position enabling switch (hereinafter referred to as "enabling
switch"), and is used to control on/off of the power supply of the robot in manual mode,
thus realizing motion enabling of the robot.
The enabling switch is installed on the back of the Teach Pendant, as shown in Fig. 1. The
motor power supply is switched on only when the enabling switch is pressed and kept in
the middle position, so that the robot is allowed to move, and you can perform Jog or run
programs. Either releasing or pressing all the way down will cut off the motor power supply.

During programming and debugging, the enabling switch should be released as soon
as possible when robot motion is not required.
2.3 Safety precautions
2.3.1 Overview
2.3.1.1 About the robot
Regardless of the motion velocity, industrial robots pose great potential hazard. A quick
and dangerous motion command may be performed following a pause or waiting during
program running. Even if you know the motion trajectory and mode of the current robot, the
motion trajectory of the robot in auto mode may still be changed by external signals
without warning.
Therefore, one must observe the safety specifications when entering the working range of
the robot.
2.3.1.2 About this section

2 Safety
XB10 Series Product Manual 9
This section will describe some basic safety specifications to the end users of the robot.
However, it cannot cover each specific circumstance due to limited space.
2.3.2 About the user's own safety
2.3.2.1 Basic principles
To ensure safety when using the robot, the following principles must be observed strictly:
The personnel are only allowed to operate the robot in manual mode when they are
within the safety zone of the robot.
You should hold the Teach Pendant in your hands when entering the safety zone of the
robot to ensure that the robot is under your control.
Pay attention to the active tools installed on the robot, such as the electric drill and
electric saw. Make sure that all these tools have stopped running before you approach
the robot.
Pay attention to the workpiece surface or the robot arm body. The motor and casing
temperature of the robot may become very high after prolonged work.
Pay attention to the gripper of the robot and the objects gripped. If the gripper is
opened, the workpiece may fall off and cause personal injury or equipment damage.
Moreover, the gripper used on the robot may be very powerful and may cause injury if it
is not used according to the specification;
Pay attention to the electrical components in the robot control cabinet. Even if the
power supply has been switched off, the remaining power in the component is still very
dangerous.
2.3.3 Safety precautions for operating the Teach Pendant
2.3.3.1 Safe storage of the Teach Pendant
The Teach Pendant no longer used should be removed from the control cabinet and
properly stored in a place that is far away from the robot workstation or control cabinet, so
as to prevent the operator from mistakenly believing that this Teach Pendant is still
connected to the control cabinet and attempting to use it to stop the robot in case of
danger.
2.3.3.2 Teach Pendant cable
The Teach Pendant and control cabinet are connected through a Teach Pendant cable.
Please comply with the following requirements when using the Teach Pendant in order to
avoid personal injury or equipment damage:
Make sure that the personnel do not stumble over the Teach Pendant cable so as to
avoid falling of the Teach Pendant or personnel.
Do not squeeze the Teach Pendant cable, otherwise, its internal cores may be
damaged.
Do not put the Teach Pendant cable on the edge of sharp objects, otherwise, the cable
sheath may be damaged.
Make sure that the bending radius of the Teach Pendant cable is greater than 100mm,
otherwise, the cable may be damaged.
2.3.3.3 Permission of using the Teach Pendant

2 Safety
10 XB10 Series Product Manual
The mode selection switch of a standard Teach Pendant is equipped with a key, i.e.
switchover between manual/auto modes is only possible using the key. Please keep the
key properly and carefully consider the user permission of the key. Generally, only those
personnel who have completed safety training and basic operation training can have the
permission to use the key.
Warning
The key to the mode selection switch on the Teach Pendant is designed for all Teach
Pendants of the same model according to standard.
Ensure that all keys are kept by qualified personnel to prevent misuse.
The user permissions for operating the Teach Pendant interface should also be
distinguished to ensure that the debugging personnel and maintenance personnel can use
the Teach Pendant correctly and reasonably according to their work.
Three user levels are built into the control system, namely operator, admin and god. The
operation permissions rank from low to high. A password must be entered when a user
with lower permission level wants to switch to a higher one; but not vice versa. A user of
higher level can modify the password of a same- or lower-level user. You cannot modify
the password of an operator. For the operation contents of different permission levels, refer
to the corresponding control system operation manual.
2.3.3.4 No Teach Pendant mode
When the No Teach Pendant mode is selected for the control system, special attention
must be paid to safety during debugging and programming. An emergency stop button
device must be installed or placed within the reach of the operator and the signal of the
emergency stop button must be routed into the safe IO interface of the robot system so
that the person can protect the safety of himself/herself and the equipment by pressing the
emergency stop button promptly in case of emergencies.
2.3.4 Safety precautions for using the control cabinet
2.3.4.1 Make sure that there is no conductive foreign objects in the control cabinet
After operations such as repair and component replacement on the control cabinet, make
sure to check if there is any conductive foreign object in the cabinet. Such objects may
cause short circuit in the control cabinet during use of the robot, thus resulting in other
dangers.
2.3.4.2 Do not supply power to the control cabinet when the cabinet door is open
Make sure that the cabinet door has been closed before switching on the robot control
cabinet.
Not all electrical devices or nodes in the control cabinet are protected. Therefore, do
not use the control cabinet when the cabinet door is open to avoid fatal danger to the
operator or equipment!
The control cabinet cannot reach the claimed protection level when the cabinet door is
open.
When the cabinet door is open, components in the cabinet are more prone to
electromagnetic interference and may generate excessive radiation to the outside, thus

2 Safety
XB10 Series Product Manual 11
directly affecting the use of the robot system.
2.3.4.3 Do not use the control cabinet for other purposes
The control cabinet is only used to control motion of the robot arm body. Using it for any
other purposes, such as standing on the cabinet body, working on the control cabinet and
using the cabinet body as a ladder, is prohibited.
2.3.5 Emergency stop button test
The emergency stop button is the only means to trigger the emergency stop as well as the
most important device to protect the safety of operators and equipment in case of
emergency.
Therefore, when the robot is put into use for the first time and when the robot is started for
the first time after an overhaul, you must first test the emergency stop button, including
testing the external emergency stop button that the integrator has connected into the robot
system, so as to confirm that pressing the emergency stop button can force the equipment
to enter the emergency stop state and executing the reset operation can exit the
emergency stop state.
Only after confirming the normal operation of the emergency stop button can you conduct
configuration or programming on the robot.
2.3.6 Resetting the emergency stop
2.3.6.1 Description
When the system is in the emergency stop state, reset it to return to its normal state. The
reset process is simple but very important. It ensures that the robot system will not be put
into production and operation in a dangerous state.
2.3.6.2 Resetting the emergency stop button
All button-shaped emergency stop devices are equipped with a safety lock mechanism,
which must be released manually after being pressed to reset the emergency stop. Most
emergency stop buttons are released by rotation and the direction of rotation is indicated
on the button surface. Some buttons also support releasing by upward pulling.
2.3.6.3 Operating procedures of resetting the emergency stop
NO.
Operation
1
Confirm that the dangerous conditions causing emergency stop have been
handled properly and the danger is removed.
2
Reset the safety device causing emergency stop.
3
Press the reset button on the control cabinet or click the reset button on the
Teach Pendant/PC interface to recover the system from the emergency stop
state. In auto mode, you can also use the system input signal to reset the system
emergency stop state.
Caution! This operation depends on the control cabinet model. For specific
operations, refer to the corresponding control cabinet product manual and control
system operation manual.
2.3.7 Band-type brake test
When the system enters the emergency stop state, the power source of the motors will be
cut off and the band-type brakes of all joints will engage. Therefore, the normal operation

2 Safety
12 XB10 Series Product Manual
of the band-type brakes helps ensure the safety of the operator and reduces risks when the
robot enters the emergency stop state.

disengaged.
3
Release the enabling switch to engage the band-type brakes.
Observe if the robot arm body keeps its previous position.
You can observe the angle value of each axis through the Teach Pendant to
confirm that the position of each joint remains unchanged.
4
Test each axis one by one.
If the position of each axis remains unchanged, it is believed that the band-type
brake function works well.
2.3.8 Manual release of the band-type brake
When the robot is in the emergency stop state, all other power supplies to the robot arm
body are cut off except the manual band-type brake release circuit. In case of emergency,
you can move the robot arm body by manually releasing the band-type brake.
A band-type bake release button is installed on the standard control cabinet. When this
function is not used, keep the protective cover of this button in place so as to prevent this
function from being triggered mistakenly.
The band-type brake release button is also installed on some models of robot arm bodies.
The method for triggering this function is different based on the models. Please carefully
check the product manual of the corresponding arm body.
Danger
Before manually releasing the band-type brake, make sure that the trapped person and
operator will not be injured during the process of moving the arm body!
Warning
When moving the robot arm body by manually releasing the band-type brake, please
note:
For small-load models, you can manually move each axis of the arm body. For
medium- and large-load models, a traveling crane, a hoist or other equipment should
be used to help move each axis of the arm body.
