4 Operating Environment Precautions
xv
termeasure for such errors, external safety measures must be provided to en-
sure safety in the system.
•
The PC or PCU outputs may remain ON or OFF due to deposits on or burning
of the output relays, or destruction of the output transistors. As a countermea-
sure for such problems, external safety measures must be provided to ensure
safety in the system.
•
When the 24-VDC output (service power supply to the PC) is overloaded or
short-circuited, the voltage may drop and result in the outputs being turned
OFF. As a countermeasure for such problems, external safety measures must
be provided to ensure safety in the system. External safety measures must
also be taken to ensure safety in the event of unexpected operation when con-
necting or disconnecting the PCU’s connectors.
Caution When positioning to a position determined using the teaching function, set the
position designation setting in the positioning sequence to absolute positioning.
If it is set to relative positioning, positioning will be performed to a position other
than the one obtained with the teaching function.
Caution Execute online edit only after confirming that no adverse effects will be caused
by extending the cycle time. Otherwise, the input signals may not be readable.
Caution Confirm the safety of the destination node before transferring a program to the
node or changing the contents of I/O memory. Doing either of these without con-
firming safety may result in injury.
Caution
Do not save data into the flash memory during memory operation or while the
motor is running. Otherwise, unexpected operation may be caused.
Caution Do not reverse the polarity of the 24-V power supply. The polarity must be cor-
rect. Otherwise, the motor may start running unexpectedly and may not stop.
4 Operating Environment Precautions
Caution Do not operate the control system in the following locations:
•
Locations subject to direct sunlight.
•
Locations subject to temperatures or humidity outside the range specified in
the specifications.
•
Locations subject to condensation as the result of severe changes in tempera-
ture.
•
Locations subject to corrosive or flammable gases.
•
Locations subject to dust (especially iron dust) or salts.
•
Locations subject to exposure to water, oil, or chemicals.
•
Locations subject to shock or vibration.
Caution Take appropriate and sufficient countermeasures when installing systems in the
following locations:
•
Locations subject to static electricity or other forms of noise.
•
Locations subject to strong electromagnetic fields.
