This operation is used when sudden deceleration or stops are frequently performed, or when the deceleration time must be shortened on loads having a large inertia.This resistor is for taking up energy during power generation braking. Invertek brake resistors are suitable for light duty loads, and can be mounted directly to the drive heatsink for a convenient, space saving installation method. RXHG resistor -----Two terminal extensions are fixed on both ends of a ceramic tube on whose surface winds wave-shaped alloy resistance wire and a high temperature-resistant and fireproof coating are applied. Bellows Resistor. When replacing a Yaskawa GPD305 inverter with a V1000, a braking resistor needs to be installed. Note 3) The allowable continuous regenerative power differs on the resistor value or power tolerance. About inverter braking resistor selection During the rapid stop of the motor, due to the effect of inertia, a large amount of regenerative power will be generated, which will directly act on the intermediate DC part of the inverter.
