POINT
Leave a 0.5-mm gap between the Motor Pulley and the electromagnetic brake. As the
countersunk screw on the electromagnetic brake protrudes, using the feeler gauge (0.5
mm), leave a gap for the protrusion.
CAUTION
• Failure to create a gap between the Motor Pulley and the electromagnetic brake may
cause the parts to rub during motor operation, causing a malfunction.
• If the set screw position is incorrect, this may cause damage on the side, and may
result in not being able to remove the part.
