The axis motor brake is normally released electrically and applied mechanically.

• A. True
• B. False
• C. Mostly not applicable, depends on model
• D. Cannot be determined

Answer: (B)

Axis motor brakes are typically spring-applied and electromagnetically released. In normal power-off conditions, a spring pushes the brake into the engaged (applied) position to hold the axis in place for safety. When you apply power to the brake coil, the magnetic force releases the brake, allowing motion. So the brake is normally applied by spring and released by electrical energization, not normally released electrically and applied mechanically. Some models can vary, but the standard design is fail-safe: brake on when power is off, released when power is applied.
