The external brake resistor of Frame A, B and C 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.
;
When the terminals +1/DC+, -/DC- are not used, please leave the terminals
open.
;
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.
