Integral Holding Brake
The following section contains a description of and specifications for a 1326AS servo motor integral
holding brake.
The disc-type brake is spring-set upon removal of power. It is designed to hold a load at rest and provide
limited braking torque for emergency stopping. The brake is not intended to be used as a positioning
brake or continuously cycled to assist in stopping a load. The brake must not be energized/de-energized
more than 90 times an hour when used as a parking brake. A parking brake is only meant to hold a
stationary load and is not intended to stop motor movement unless a power interruption occurs.
