Moving the Manipulator while releasing the electromagnetic brake involves risk as described below.
It is recommended to move the Manipulator using Jog & Teach.
⚫ Normally, release the brake of joints one by one. Take extra care if you need to release the brakes of two or more joints
simultaneously. Releasing the brakes of two or more joints simultaneously may cause hands and fingers to be caught
and/or equipment damage to or malfunction of the Manipulator as the arms of the Manipulator may move in unexpected
directions.
⚫ Be careful of the arm falling when releasing the brake.
While the brake is being released, the Manipulator’s arm falls by its own weight.
The arm falling may cause hands and fingers to be caught and/or may cause equipment damage to or malfunction of
the Manipulator.
Also, pay attention to the following points at the encoder initialization.
⚫ The Joint #1 and Joint #4 have no mechanical stops and they may be rotated more than 360 degrees. If the encoder
initialization is performed with improper posture, the Manipulator moves outside the operation range. If the Manipulator
was moved outside the operation range, the internal wiring may be damaged by being twisted or pinched and it may
result in Manipulator malfunction.
