· Dynamic braking is used when energy needs to be dissipated periodically, and regeneration is generally preferred when the motor is frequently acting as a generator. From an appliion standpoint, overhauling loads (a condition where the load is moving faster than the designated motor speed), such as conveyors and cranes, cause energy to be generated continuously and make .

·, 11:42 AM. Originally posted by Sparky_NY. The factory "dynamic brake module" connects to the VFD with just 2 wires. The terms are the dc bus outputs. Apparently all operating voltages are derived from that for braking. I was thinking a avalanche diode, a few resistors, and the transistor should about do it.

· I have 2HP Teco VFDs on both a mill and a lathe. Both of them stop nicely with braking resistors. The Teco manual calls for a 100 ohm 150 watt braking resistor for the 2HP unit, a 70 ohm 200 watt resistor for the 3HP model. My guess is that your VFD would use the same value resistors. They're pretty standard sizes.

· Braking transistor mounted inside a VFD . Moreover, the braking transistor duty rating of other manufacturers' drives is often less than , which means that the drive or braking module may need to be oversized in order to handle the braking current. Given these considerations, it is easy to see why the F5 is the VFD of choice for many OEMs.

· The HP output on the motor driven by a VFD is this. From zero to rated (nameplate) speed, the hp is proportional to the speed. 50% speed = 50% hp. Above the rated speed, the hp is constant at the rated HP. Most modern motors can be run at least up to 150% or more. The motor on my mill/drill is a 1725 motor.
