9.4.2. Motor electromagnetic / electromechanical brake
Electromechanical brakes are needed in critical applications where the disconnection of the motor or a lack of
electric braking could be dangerous or harmful (i.e. falling suspended loads). Everest XCR Servo Drive includes
a brake output on the I/O connector J2. The brake output is an N-Channel MOSFET that can be PWM modulated to
reduce effective brake voltage and thus power consumption when energized
.
Its operation is usually configured for normally locked electromechanical brakes; that is, brakes that by default
block the movement of the motor shaft when not powered. This kind of brakes increase the safety of the
application, because in a drive power failure, the switch would be opened therefore the brake activated. Main
ratings of the brake switch are detailed in the next table:
