Connectors and pin assignment
• The pin assignment of the connectors is as viewed from the cable connector wiring section.
• For the STO I/O signal connector (CN8), refer to the following.
• For the CN3 connector, securely connect the shielded external conductor of the cable to the ground plate
and fix it to the connector shell.
The servo amplifier front view shown is that of the MR-J4-60GF-RJ or less. Refer to the following for the appearances and
connector layouts of the other servo amplifiers.
The frames of the CN2, CN2L, and CN3 connectors are connected to the protective earth terminal in the servo amplifier.
*1 The MR-J4-_GF_ servo amplifier does not have CN2L connector.
*2 This is a connector of 3M. Refer to the following for connections of external encoders.
