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.
Connecting terminating resistors
(1) GOT side
When connecting a servo amplifier to the GOT, a
terminating resistor must be connected to the GOT.
(a) For GT16, GT15, GT12
Set the terminating resistor setting switch of the
GOT main unit to "No".
(b) For GT14, GT11, GT10
Set the terminating resistor selector to "330 ".
For the procedure to set the terminating resistor, refer
to the following.
