OVERVIEW
The ServoTube brake provides a solution to power down parking of vertical axes and controlled deceleration of axes
during power fail conditions. The brake is a bolt-on addition to any STA25 or XTR25 forcer and is IP67 rated. It is a
unidirectional self-jamming design, which uses the motor’s motion to create the necessary forces for braking the
system. To minimize size, the brake is designed to be reset by the motor itself. Once reset, it is held off by a compact
24V electromagnet. The motor is then free to operate as normal until the release of power to the brake.
OPERATION
NOTE: The following release and activate sequences are available as automatic Indexer routines in Copley’s CME 2
amplifier configuration software.
From power-on, the brake must be released before normal operation of the motor.
Release:
1. Apply power to the forcer and drive the thrust rod UP by applying sufficient force to overcome the braking
action (70-80N)
2. Continue driving UP until the STOP on the thrust rod activates the BRAKE RELEASE. Activation can be
detected by the controller when velocity=0 or there is no change in position.
3. Apply 24V to brake solenoid
4. Wait 100ms
5. The brake will now hold off and the forcer can operate as normal
Activate:
1. Remove 24V from the brake solenoid. The thrust rod will fall a very short distance before the brake activates
2. Wait 100ms
3. Disable the servo to remove power from the forcer
