15. INVERTER CONNECTION
15.3 Connection Diagram
*1 Connect a terminating resistor jumper to RDB and RDR which are assigned in the FR-A5NR of the inverter located farthest from
the GOT.
The terminating resister jumper is packed together with the FR-A5NR.
*2 For GT16, GT15 and GT12, set the terminating resistor of GOT side, which will be a terminal, to "Enable".
For GT14, GT11 and GT10, set the terminating resistor of GOT side, which will be a terminal, to "330 ".
1.4.3 Terminating resistors of GOT
*1 For GT16, GT15 and GT12, set the terminating resistor to
"Disable".
For GT14, GT11 and GT10, set the terminating resistor to
"330 ".
1.4.3 Terminating resistors of GOT
*2 RDA2, RDB2, SDA2 and SDB2 terminals of the RS485
terminal block (built into the inverter) cannot be used.
