
Precautions when preparing a cable
(1) Cable length
The length of the RS-485 cable must be 500m or less.
(2) GOT side connector
For the GOT side connector, refer to the following.
1.4.1 GOT connector specifications
(3) Inverter connector specifications
(a) Pin layout in the PU port
The contents inside ( ) indicate symbols described
in the inverter manual.
The pins number 2 and 8 (P5S) are connected to
the power supply for an operation panel or a
parameter unit.
Do not use them in RS-485 communication.
(b) Connector of cable between FREQROL Series
inverters
Use the commercial connectors and cables shown
in the table below or the comparable
products.(Refer to the manual for the inverter.)
(4) Terminal block layout in the FR-A5NR computer link
option
Attach this option to the A500 and F500 Series.
(5) Terminal block layout in the FR-E7TR control
terminal option
Mount the FR-E7TR to the E700 series.

Connecting terminating resistors
(1) GOT side
When connecting a PLC to the GOT, a terminating
resistor must be connected to the GOT.
(a) For GT16, GT15, GT12
Set the terminating resistor setting switch.
(b) For GT14, GT11, GT10
Set the terminating resistor selector switch.
For the procedure to set the terminating resistor, refer
to the following.

To the GOT or
the previous
inverter
Set the terminal 2/SG switch to the
right position (ON) to change the
terminal 2 to the terminal SG.
