Caution
Provide safety measures in external circuits (i.e., not in the Programmable Controller or
Position Control Unit) to ensure safety in the system if an abnormality occurs due to
malfunction of the PLC, malfunction of the PCU (Position Control Unit), or external factors
affecting the operation of the PLC or PCU.
Not providing sufficient safety measures may result in serious accidents.
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.
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.
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.
Do not save data into the flash memory during memory operation or while the motor is
running. Otherwise, unexpected operation may be caused.
Do not reverse the polarity of the 24-V power supply. The polarity must be correct.
Otherwise, the motor may start running unexpectedly and may not stop.
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.

Unexpected operation, however, may still occur for errors in the I/O control section,
errors in I/O memory, and other errors that cannot be detected by the self-diagnosis
