Preface
Thank you for purchasing Inovance MDBUN series braking unit.
Inovance MDBUN series braking unit applies to the applications where an AC drive or
servo drive (hereinafter referred to as "drive") needs to perform deceleration, positioning
or braking operation. When the drive performs braking, kinetic energy is converted to
electric energy which is fed back to the drive due to the mechanical inertia of the load.
This will cause rising of the DC bus voltage of the drive. Therefore, a braking unit is
required to ensure normal running of the drive. The regenerative energy is consumed by
the braking resistor, preventing the drive from stopping or even being damaged due to
overvoltage protection.
Inovance MDBUN series braking unit provides full protection functions, such as
overcurrent, overheat, and braking unit open-circuit and short-circuit protection. It
supports the setting of parameters including braking start/stop voltage, and braking rate.
Multiple braking units can be deployed in master/slave mode to meet the braking
requirements of high power drive.
Inovance MDBUN braking unit also applies to large-inertia applications that require
sudden stop, for example, such as elevators, textile machines, paper making machines,
centrifuges, wire drawing machines, winding machines, proportional linkage systems, and
crown blocks.
