CAUTION

The inverter will be damaged if power is applied to the inverter output terminals (U, V, W). Never per- form such wiring.

When connecting the dedicated brake resistor (FR-ABR), remove jumpers across terminals PR-PX (5.5K or less). Set "1" in Pr. 30 "regenerative function selection". Refer to the Instruction Manual (detailed) for details.

When connecting the brake unit (FR-BU, BU), remove jumpers across terminals PR-PX (5.5K or less). Refer to the Instruction Manual (detailed) for details.
