(4) Synthesis of movements in the same direction
In some programs, the machine is operated by synthesizing two movements (the FOS and PFOS with the
AWAKE instruction of LUNA).
When the teaching points to be synthesized are aligned on the same line, the machine can step out.
When such a movement is experienced, the application program must be modified.
(5) Eccentric loading
When a load (tool, work, etc.) is very eccentric or far from the mounting surface, stepping out can occur
even though the load is lower than the maximum payload. If the weight balance cannot be improved,
reduce the operating speed.
(6) Mounting screw
When a mounting screw is so long that the tip of the screw touches the cover or other object, it can cause
stepping out. You can detect this trouble by listening for a rubbing sound or looking for scars. Check for
these before use.
(7) Belt tension
If the belt tension becomes abnormal, contact your Sony dealer from which you purchased the machine,
or contact Sony Max Corporation FA Service.
(8) When the machine is operated at low temperature
In early morning during winter, the room temperature may fall to 0
°C or lower. The temperature inside
the machine takes time to rise even though the temperature of the room can be increased by using a
heater.
In this case, run the machine for half an hour at half the specified speed, or wait until the temperature of
the machine rises to the temperature of the room.
