Name Overview
Power regeneration
common converter
(FR-CV )
Provides a large braking capability. Install this as required.
Power regeneration
converter
(MT-RC )
Brake unit
(FR-BU2, FR-BU )
Allows the inverter to provide the optimal regenerative braking
capability. Install this as required.
Resistor unit
(FR-BR , MT-BR5 )
A USB (Ver. 1.1) cable connects the inverter with a personal
computer.
USB connection
A USB memory device enables parameter copies and the trace
function.
Improves the braking capability of the inverter built-in brake.
Remove the jumper across the terminals PR and PX to connect this.
High-duty brake resistor
(7.5K or lower)
(FR-ABR )
Always install a thermal relay when using a brake resistor whose
capacity is 11K or higher.
Install this to reduce the electromagnetic noise generated from the
Noise filter
inverter. The noise filter is effective in the range from about
(ferrite core)
0.5 MHz to 5 MHz.
(FR-BSF01, FR-BLF)
A wire should be wound four turns at maximum.
Induction motor Connect a squirrel-cage induction motor.
Contactor
Connect this for an application where a PM motor is driven by the
load even while the inverter power is OFF. Do not open or close the
Example:
contactor while the inverter is running (outputting).
No-fuse switch (DSN type)
Use the specified motor. An IPM motor cannot be driven by the
IPM motor (MM-CF)
commercial power supply.
