Setup
ATTENTION: The dynamic brake unit contains a
thermostat to guard against overheating and component
damage.
If the duty cycle, torque setting and/or ambient temperature
exceeds the specifications listed in this publication, the
thermostat is designed to trip and disable the brake.
If reduced braking torque represents a potential hazard to
personnel, auxiliary stopping methods must be considered in
the machine and/or control circuit design.
