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
deceleration ramps, short deceleration time, too low brake torque or
requiring increased brake torque.
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.
