Precautions when preparing cable
(1) Cable length
The length of the RS-422 cable must be 30m or less.
(2) GOT side connector
For the GOT side connector, refer to the following.
1.4.1 GOT connector specifications
(3) Servo amplifier connector
Use the connector compatible with the servo amplifier.
For details, refer to the following.
See the technical data of the servo amplifier to
be used.
(a) Servo amplifier connector specifications
• Pin layout in the Modular connector
• Connector of cable between MELSERVO Series
servo amplifiers
• Use the commercial connectors and cables
shown in the table below or the comparable
products.
(Refer to the manual for the servo amplifier.)
Connecting terminating resistors
(1) GOT side
Set the terminating resistor setting switch to "Disable".
For the procedure to set the terminating resistor, refer
