Precautions For Powering Off Only A Desired Servo Amplifier - Mitsubishi Electric MELSEC iQ-R Series Migration Manual

1.4.4 Precautions for powering off only a desired servo amplifier

Changing the servo amplifier connection method from SSCNET (metal cables) to SSCNETIII/H
(optical fiber cables) makes the Motion controller communicate with servo amplifiers on the
second axis and after via the servo amplifier of a preceding axis. Thus, powering OFF the servo
amplifier on a preceding axis cuts off communication with all servo amplifiers on subsequent
axes.
Use the SSCNETIII/H compatible MR-MV200 optical hub unit for powering off only a desired
servo amplifier.
Refer to section 1.4.5 for details of the MR-MV200 optical hub unit.
