injury or death.
I. General Information
The function of the HBU braking unit is to divert into a braking resistor the regenerative energy produced in the
process of decelerating the motor, converting that energy into heat. Regenerative energy flows from the motor into the
inverter DC Bus, manifested as increased bus voltage. The advantage gained using the HBU is improved braking
performance and shorter deceleration time of the load.
Before you use the HBU braking unit, please read through this manual and please contact your distributor if you
have any questions. This manual will provide you the necessary information for installation, operation,
troubleshooting and repair of the HBU braking unit.
A. Inspection
Please check that the model number is the same as what you ordered BEFORE opening the box. Then, check the
contents for any sign of defect or damage during transport. If there is any problem, please contact your Hitachi
distributor immediately.
