emergency stop and park brake duty. Normal braking of a
load is still controlled by the adjustable frequency drive
dynamic brake.

Spring-loaded brakes are safety brakes that continue to
work in the event of power failure or usual wear. Since
other components could also fail, take suitable safety

precautions to avoid any injury to persons or damage to
objects caused by operation without a brake.
