o obtain the motor moment of inertia with a brake,
add the holding brake moment of inertia to the rotor
moment of inertia. The rated power rate and angular
acceleration of the motor will change according to the
he holding brake is only used to hold the load and
cannot be used to stop the servomotor.
o not use the holding brake when the servo is on.
Failure to observe this caution may result in an over
r a decrease of brake life.
