1 Safety Precautions
• Take the following measures when teaching, correcting, inspecting, or adjusting the
manipulator when the motor power supply is ON:
(a) Appoint a personnel to stay beside the emergency stop button of the NX100 and
perform the operations holding the programming pendant with the emergency stop
button.
(b) Before the operation, verify the correct robot motion and that the emergency stop
works.
• Observe the following precautions during an automatic operation:
(a) Do not enter inside the safeguards during operation.
(b) Confirm the following before starting the operation:
• No person is inside the manipulator working envelope.
• No obstacles such as unnecessary workpieces and tools are inside the
manipulator working envelope.
• The manipulator is in its standby position.
(c) When any abnormality occurs, immediately press the emergency stop button to stop
the manipulator.
(d) Before entering inside the manipulator working envelope, be sure to stop the
manipulator and turn OFF the main power supply to the NX100.
• Brake release (Option)
A braking system is provided on each axis of the manipulator to hold the arm in its
position when a failure or fault occurs. When the brake is activated, the manipulator
cannot be moved manually even if the power is OFF. To change the posture of the
manipulator after a failure or fault, the brake can be released by the operation from the
controller.
When the brake is released with the manipulator's power OFF, each axis falls down
because of the arm weight. While two or more people are holding the arm in position
before releasing the brake, change the posture of the manipulator within the minimum
motion range.
Use the brake release function only when absolutely necessary.
Any modification of the MOTOMAN-EPX1750 & EPX2050, and the following is strictly
prohibited:
1. Explosion-proof devices and system installation
2. Safeguards and the safety devices mounted on these safeguards
3. Emergency stop button, and other safety devices
4. Robot control system such as the NX100 robot controller, the manipulator drive
section and the power transmission section
