Name Description
AC power input Connect to the commercial power supply.
Keep these terminals open when using the high power factor converter (FR-HC) or
power regeneration common converter (FR-CV).
Inverter output Voltage ouput of the inverter
(3~, 0V–power supply voltage, 0.2–400Hz)
Brake resistor Connect a brake resistor (FR-ABR) across terminals P/+ and PR.
connection (The brake resistor can not be connected to the FR-E720S-008SC and 015SC.)
Brake unit connection Connect the brake unit (FR-BU2), power regeneration common converter (FR-CV)
or high power factor converter (FR-HC).
DC reactor connection Remove the jumper across terminals P/+ and P1 and connect a DC reactor.
PE For earthing the inverter chassis. Must be earthed.
