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, 0.2–400 Hz)
Brake resistor con- Connect a brake transistor (FR-ABR, MRS) across terminals + and PR.
nection (The brake resistor can not be connected to the FR-E720S-008 and 015.)
Brake unit connection Connect the brake unit (FR-BU2), power regeneration common converter
(FR-CV) or high power factor converter (FR-HC).
DC reactor Remove the jumper across terminals + and P1 and connect a DC reactor.
