Basic safety points

Besides reading this instruction manual and the controller user's manual, also be sure to
handle the equipment correctly while paying sufficient attention to safety.
Points regarding safety in this instruction manual only list items involving this product.
Please refer to the controller instruction manual for information regarding safety when
using this unit with the controller.
It is not possible to detail all safety items within the limited space of this manual. So it is
essential that the user have a full knowledge of basic safety rules and also that the opera-
tor makes correct judgments on safety procedures during operation.
Industrial robots are highly programmable, mechanical devices that provide a large de-
gree of freedom when performing various manipulative tasks. Failure to take necessary
safety measures or mishandling due to not following the instruction in this manual may
result in trouble or damage to the robot and injury to personnel (robot operator or service
personnel) including fatal accidents.
Important caution points in this manual are from hereon indicated by the term:

System design safety points

! CAUTION
When communication errors occur in the PROFIBUS system, check the status of
the network system and the controller beforehand by referring to the PROFIBUS
instruction manual and this instruction manual. Also use this communication sta-
tus information to contrive circuits and interlocks in the sequence program so that
the system including the controller will operate safely.
! CAUTION
Emergency stop signals may sometimes interrupt register operation in the
PROFIBUS unit, however this is merely a software control process and is in no
way a problem. Therefore, we strongly advise contriving a hardware interlock
circuit connected to the emergency stop pin contacts in the parallel I/O of the
controller.
! CAUTION
Do not bundle control lines or communication cables together or in close contact
with main circuit or motor/actuator lines. As a general rule, maintain a gap of at
least 100mm. Noise in signal lines may cause faulty operation.
