Regenerative brake selection
• When performing frequent start and stop operation, usage rate of the regenerative brake can be increased by using the
optional high-duty brake resistor (FR-ABR) or the brake unit (FR-BU2, BU, or FR-BU).
• The multifunction regeneration converter (FR-XC in power regeneration mode) or power regeneration common converter
(FR-CV) is used for the continuous operation in the regenerative status. The multifunction regeneration converter (FR-XC
in common bus regeneration mode) and high power factor converter (FR-HC2) can also be used to reduce harmonics,
improve power factor, and operate continuously during regenerative driving. The multifunction regeneration converter (FR-
XC), power regeneration common converter (FR-CV), and high power factor converter (FR-HC2) cannot be used with the
safety communication model and the IP67 model.
• When the FR-E8DS is installed, the reset operation when the power is supplied to the main circuit while 24 V external
power is supplied to the inverter can be selected. (Standard model and Ethernet model)
