Drives AF-60LP ™ Micro Drive Dynamic Braking Resistors

Section 15

Dynamic Braking allows for faster deceleration rates then could be achieved via a coast to stop. Dynamic braking consists of the internal drive brake chopper and separate add- on dynamic braking resistors. Important application notes: - The AF-60LP ™ Micro Drive dynamic braking can be used for stopping a load with an inertia equal to or less than the applied motor's rotor inertia. - High inertia or overhauling loads may cause extended deceleration times which could cause overheating and tripping of the drive. - The dynamic braking is not a holding brake. It does not prevent a motor at rest from rotating. Note: Refer to the drives' Operating Instruction for installation and connection details.
