models, use the R/L1 and S/L2/N terminals to connect power cables.
Grounding terminal for connecting inverter. There are 3 terminals in cooling fin or
mounting part of EMC plate.
240V class : Three-phase 200 to 240V-50/60Hz
: Single-phase 200 to 240V-50/60Hz
500V class : Three-phase 380 to 500V-50/60Hz
* Single-phase inputs are R/L1 and S/L2/N terminals.
Connect to three-phase motor.
Connect to braking resistors.
Change parameters , , ,  if necessary.
This is a positive potential terminal in the internal DC main circuit.
DC common power can be input between PA/- terminal and PC/- terminal.
This is a negative potential terminal in the internal DC main circuit.
DC common power can be input between PC/- terminal and PA/+ terminal.
Terminals for connecting a DC reactor (DCL: optional external device). Shorted by a
Shorting-bar when shipped from the factory. Before installing DCL, remove the
shorting-bar.
