*1) Electronic thermal protection is accordance to derating.
*2) The rated input current is the value when the drive is operated in the rated output current. The value of the impedance at the supply side changes
due to the wiring, breaker, input reactor, etc.
*3) The power supply capacity is the value of the rated output current at 440V. The value of the impedance at the supply side changes due to the wiring,
breaker, input reactor, etc.
*4) It is recommended to set the carrier frequency settings [bb101]/[bb201] equal or greater than the (maximum output frequency x 10)Hz.
For induction motor IM, it is recomended to set the carrier frequency to 2 kHz or more except V/f control. For synchronous motor (SM)/Permanent
magnet motor (PMM), it is recomended to set the carrier frequency to 8 kHz or more.
*5) Usually an external regenerative braking unit is required. However, with an optional built –in chopper braking ciruit and external discharge resistor
can eliminate a external regenerative unit. The built-in chopper braking circuit is offered by order. In order to purchase, contact to the nearest sales
office
*6) The key height of keypad are exclued from dimensions. When an option is connected, the depth is increased. Refer to the each optional instruction.
