Safety Precautions
3
• The PLC will turn OFF all outputs when its self-diagnosis function detects
any error or when a severe failure alarm (FALS) instruction is executed.
As a countermeasure for such errors, external safety measures must be
provided to ensure safety in the system.
• The PLC 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
countermeasure for such problems, external safety measures must be
provided to ensure safety in the system.
• When the 24-V DC output (service power supply to the PLC) is over-
loaded 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 connecting 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 position-
ing. 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
confirming 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.
!Caution
Make sure the unit version of the Position Control Unit is 2.3 or later before
using the CW/CCW Pulse Output Selection Function. Otherwise, the pulse
output may be in the opposite direction from what was intended and the
machine may be damaged.
