3.8 Movement without drive power

In case of emergency or occurrence of abnormal situations, you can configure the setting in such a way that the drive power of the robot is cut off and the axes can be moved for any workers isolated in the hazard area to make an emergency escape.

[Caution]

• If you release an axis of the robot when driving power is not applied to the robot, the axis may sag or drop. For safety, hold the axis using a device such as a crane that can support the axis before releasing it.

• To prepare for emergencies and abnormal situations, all workers that install, use, and repair the robot system must undergo training in movement without driving power

Movement without drive power can be used by using the [Brake Release Function] menu of the teach pendant.

1. Return the safety input with the robot motor powered off.

2. Touch the [Set up > 3 : Robot parameter > 36 : Brake Release Function] menu on the teach pendant screen.

3. Check the robot’s condition and release the brake on the desired axis.

• To release the brake for each asxis, touch the [Lock] button of the desired axis. The brake of the corresponding axis is released only while touching the [Lock] button. When you release the [Lock] button, the brake is locked again.

• To release the brakes for all axes at once, touch the [All brake release on] button. If you touch the [All brake release off] button, the brakes of all axes are locked at once.

[Caution]: You can release the brake of the axis only in the [Brake Release Function] menu of the teach pendant. All brakes are locked as soon as you leave this menu.
