■2. Precautions when preparing a cable
(1) Cable length
The length of the RS-485 cable must be 1m or less.
(2) GOT side connector
For the GOT side connector, refer to the following.
➠
(3) PANASONIC servo amplifier side connector
Use the connector compatible with the PANASONIC servo amplifier.
For details, refer to the user's manual of the PANASONIC servo amplifier.
■3. Connecting terminating resistors
(1) GOT side
(a)
For GT27, GT25(Except GT2505-V), GT23
Set the terminating resistor setting switch of the GOT main unit to "Disable".
(b)
For GT2505-V
Set the terminating resistor selector to "110Ω".
For details of terminating resistor settings, refer to the following.
