Notes for Safe Operation

• 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.

Figure 1: 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.

Figure 2: Release of Emergency Stop

• Observe the following precautions when performing teaching
operations within the P-point maximum envelope of the
manipulator:

– Be sure to use a lockout device to the safeguarding when going

inside. Also, display the sign that the operation is being
performed inside the safeguarding and make sure no one closes
the safeguarding.

– 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 Zeroing Function

1.1 Outline

1 Zeroing Function

Zeroing function automatically allows for the restoration of the home
position data when the manipulator’s home position data disappear.
(Optional function)

This function only applies to the manipulator which was ordered to be
equipped with the zeroing function and shipped.

1.1 Outline

The DX100 stores the manipulator home position based on the pulse
value of each axis encoder. Since the home position is already set and
registered before shipment, zeroing operation does not need to be
performed at the normal operation. However, zeroing operation needs to
be performed to restore the home position since the home position data
disappear when you perform the following operations, or the followings
occur.

163471-1CD

• Replacement of Motors

• Replacement of Encoders

• Backup Battery Exhaustion in the Manipulator

The home position data is stored by the backup battery. If
the battery is exhausted, the home position data disappear
again when turning OFF the DX100 power even when the
zeroing operation is performed.

Be sure to replace the battery periodically. For the battery
replacement, refer to “Maintenance and Inspection” of
“MOTOMAN-MH50 INSTRUCTIONS”.

The home positioning cannot be performed accurately by
the zeroing operation if changing the combination of the
manipulator and the DX100.
