avoid this, it is recommend to use a serial connected AC input
reactor(6%) at the AC Motor Drive mains input side to reduce the current
and improve the input power efficiency.
; Connect a brake resistor or brake unit in applications with frequent

Brake resistor
(optional)
; The external brake resistor should connect to the terminals (B1, B2) of
AC motor drives.
; For those models without built-in brake resistor, please connect external
brake unit and brake resistor (both of them are optional) to increase
brake torque.
; DC+ and DC- are connected by common DC bus, please refer to
Chapter 5-1(Main Circuit Terminal) for the wiring terminal specification
and the wire gauge information.
; Please refer to the VFDB manual for more information on wire gauge
when installing the brake unit.
