Power regeneration
common converter
(FR-CV
)
Provides a large braking capability. Install this as required.
2-89
Power regeneration
converter
(MT-RC
)
2-90
Brake unit
(FR-BU2, FR-BU
)
Allows the inverter to provide the optimal regenerative braking
capability. Install this as required.
2-82
Resistor unit
(FR-BR
, MT-BR5 )
USB connection
A USB (Ver. 1.1) cable connects the inverter with a personal
computer.
A USB memory device enables parameter copies and the trace
function.
2-58
High-duty brake resistor
(FR-ABR
)
Improves the braking capability of the inverter built-in brake.
Remove the jumper across the terminals PR and PX to connect this.
(7.5K or lower)
Always install a thermal relay when using a brake resistor whose
capacity is 11K or higher.
2-77
Noise filter
(ferrite core)
(FR-BSF01, FR-BLF)
Install this to reduce the electromagnetic noise generated from the
inverter. The noise filter is effective in the range from about
0.5 MHz to 5 MHz.
A wire should be wound four turns at maximum.
3-6
Induction motor Connect a squirrel-cage induction motor.
⎯
Contactor
Example:
No-fuse switch (DSN type)
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
contactor while the inverter is running (outputting).
⎯
IPM motor (MM-CF)
Use the specified motor. An IPM motor cannot be driven by the
commercial power supply.
