Terminals for connecting DC reactor, external brake resistor and DC circuit
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 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+ and -/DC- 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.
