Precautions when preparing a cable
(1) Cable length
(a) The length of the RS-422 cable used for connecting the
connected equipment to the communication converter
The length of the RS-422 cable must be 500m or
less.
(b) The length of the RS-422 cable used for connecting the
connected equipment to the GOT.
The total distance (between GOT and controllers)
of RS-422 cable must be 13m or less.
(2) Connector conversion box side connector
For the connector conversion box side connector, refer
to the following.
6.6 Connector Conversion Box
(3) External cable side connector
For the connector specifications of the external cable
side, refer to the following.
8.2 External Cable, Relay Cable
(4) JTEKT PLC side connector
Use the connector compatible with the JTEKT PLC side
module.
For details, refer to the JTEKT PLC user's manual.
