Terminals for connecting DC reactor, external brake resistor, external brake resistor
and DC circuit
 This is the terminals used to connect the DC reactor to improve the power factor. For
the factory setting, it connects the short-circuit object. Please remove this short-circuit
object before connecting to the DC reactor.
Figure 5-2
 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.
Figure 5-3
 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 ter1, +2 and - are not used, please leave the terminals open.
 DC+ and DC- are connected by common DC BUS, please refer to Section 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.
