NEMA Type 1 Dynamic Brake

Cat. Nos. 1397-DB-AxxxE — 240VDC

1397-DB-BxxxE — 500VDC

What This Option

Provides

The 1397 NEMA Type 1 Dynamic Brake provides a self contained

NEMA Type 1 enclosed assembly that is wired to the 1397 drive.

Where This Option Is

Used

Each NEMA Type 1 Dynamic Brake is sized to a 1397 drive as

detailed below. For 230V AC drive ratings above 30HP (22kW) and

460V AC drive ratings above 60HP (45kW), a 1397 IP00 (open style)

Dynamic Brake should be used.

1397 NEMA Type 1 Dynamic Brake Operation Dynamic braking slows down a rotating DC motor and its load. It is an "uncontrolled" process. During dynamic braking, the motor armature is disconnected from the drive. A resistor is placed across the motor’s rotating armature (now acting as a generator), and the resulting current causes braking torque in the motor. The motor will decelerate, even with a drive failure, as long as motor field excitation is maintained.
