Terminal function description
Connect these terminals to the commercial power supply.
Do not connect anything to these terminals when using the high power factor
converter (FR-HC2), multifunction regeneration converter (FR-XC)
power regeneration common converter (FR-CV).
Connect these terminals to a three-phase squirrel cage motor or a PM motor. —
Connected to the AC power supply terminals R/L1 and S/L2. To retain the
fault display and fault output, or to use the high power factor converter (FR-
HC2), multifunction regeneration converter (FR-XC)
regeneration common converter (FR-CV), remove the jumpers across
terminals R/L1 and R1/L11 and across S/L2 and S1/L21, and supply external
power to these terminals.
The power capacity necessary when separate power is supplied from R1/
L11 and S1/L21 differs according to the inverter capacity.
FR-F820-00630(15K) or lower or FR-F840-00380(18.5K) or lower: 60 VA,
FR-F820-00770(18.5K) or higher or FR-F840-00470(22K) or higher: 80 VA
Connect the brake unit (FR-BU2, FR-BU, BU), power regeneration common
converter (FR-CV), power regeneration converter (MT-RC), high power
factor converter (FR-HC2), multifunction regeneration converter (FR-XC), or
DC power supply (under DC feeding mode).
Remove the jumper across terminals P/+ and P1, and connect a DC reactor.
When a DC reactor is not connected, the jumper across terminals P/+ and
P1 should not be removed.
Always connect a DC reactor, which is available as an option.
For earthing (grounding) the inverter chassis. Be sure to earth (ground) the
inverter.
