21. n E __ _ n EY Introduction The DURAPULSE Dynamic Brake Units are used with the DURAPULSE AC Drives to enable the AC motor and its load to be decelerated more rapidly to zero speed than what normally can be achieved without the brake unit Applications with high inertia type loads tend to cause the motor to regenerate energy back into the AC drive This regeneration causes the AC drive s internal DC bus voltage to rise and if left unchecked can cause an over voltage trip The brake unit is designed to continuously monitor the drive s DC bus voltage and when the voltage exceeds a predetermined level depending on the supply voltage the brake unit dissipates the excess energy into an external resistor in the form of heat The Dynamic Brake Unit is available in two different voltage classes 230V or 460V The brake units can be set up for multiple unit operation using the MASTER SLAVE configuration that will achieve the power rating required for the larger AC drive and motor combinations Unpacking After receiving the DURAPULSE Dynamic Brake Unit GS 2DBU or GS 4DBU please check for the following e Make sure that the part number indicated on the package corresponds with the part number of your order e Make sure that the package includes the DURAPULSE dynamic brake unit and the DURAPULSE Dynamic Brake Unit User Manual e Inspect the contents to insure they were not damaged during shipment DURAPULSE Dynamic Brake
