description
- The new multi-purpose brake is a microprocessor-based solid state brake designed to eliminate the problems common to traditional DC injection brakes. To eliminate blown fuses and welded contacts the microprocessor senses when AC is no longer present before turning "on" the injection.A faster zero speed sensing circuit turns off the injection as soon as the motor stops reducing motor heating.
applications
- Applications: stopping coasting loads such as chippers, saws, cutting tools and conveyors
- It can also be used to stop windmilling fans before starting
- Stopping time: The Baldor dynamic brake can stop the motor faster than motor will start (at 460 V)
- However, this could damage the motor
- It is best that the motor should not stop any faster than the motor starts
- Stopping the motor too fast or too
- Motor sizing Each stop with a dynamic brake should be treated as a start for calculating duty cycle and for sizing the motor
- The brake does not have a duty cycle limit
- Holding brake: A solid state brake is not a substitute for a mechanical holding brake
- Motor types The multi-purpose brake has been designed to operate on three-phase induction motors
- Brake sizing: use the motor FLA and operating voltage to size the brake
- All Baldor multi-purpose brakes can be used on high inertia loads
- Extended stopping times are available for use on high inertia loads
features
- Simple wiring for start/stop/jog push buttons
- Four different operating modes:
- Control transformer is standard on the panel
- Microprocessor-based control provides the control with accurate zero speed sensing to reduce motor heating, AC sensing at the motor eliminates the need for I²T fuses, mechanical and electrical interlocks and two independent braking magnitudes one can be u
- Compliance to ANSI 01.1-1992 woodworking machinery safety requirements
- UL® listed and cUL Canada listed

caution
- WARNING: A DC injection brake is not a replacement for a mechanical or safety brake for emergency stopping.
