Sscnet Cables And Connection Method - Mitsubishi Electric Q172DCPU User Manual

2 SYSTEM CONFIGURATION
2.4.8 SSCNET cables and connection method
This section describes how to connect between the Motion CPU module and servo
amplifiers.
Between the Motion CPU module and servo amplifiers is connected by SSCNET
cable. When using the Q172DCPU, only 1 SSCNET cable for connection to servo
amplifier can be used. (Connect to CN1.) When using the Q173DCPU, up to 2
SSCNET cables for connection to servo amplifier can be used. (Connect to CN1 and
CN2.)
Up to 16 servo amplifies can be connected to 1 SSCNET cable.
(However, when using the Q172DCPU, up to 8 servo amplifiers can be connected.)
