Chapter Five Alarming and Handling
z Personnel involved in examination and repair must possess corresponding professional
knowledge and abilities.
z Do not touch driver and motor at least 5 minutes after the power has been cut off for fear of
electric shock and heat injury.
z After alarm for the failure of drive unit occurs, the unit can only put into operation after the
trouble is shot according to the alarm code.
z Do confirm that the SON (servo ready) signal is invalid before resetting the alarm for fear that
the sudden staring of motor may cause accidents.
