3.5 Configuration Using a SIO Converter
If any of the following conditions applies, use a SIO converter to connect the teaching pendant, PC or PLC’s
communication module:
[1] The actuator’s rear cover cannot be reached and therefore the teaching pendant or PC cannot be connected.
[2] Want to execute movement operation or parameter edit for all axes when multiple axes are connected to the
single equipment.
[3] Want to operate the actuator via serial communication using the PLC’s communication module.
Note: Do not connect a teaching pendant and a PC at the same time. If both are connected at the
same time, a communication error (message level) will occur.
