11 Brake Function & Manually Releasing the Brake
Please be sure to review "Important Brake Usage Guidelines" (
11.1 About the Brake Function
RGM is equipped with a power-off park brake, meaning that the brake is mechanically engaged and prevents
rotation (within its in/- 0.9° backlash characteristic) of the output plate when no power is applied. In
normal operation, when the RGM drive is enabled by the user’s controller, the energized brake coil will
release, accompanied by an audible "click". Normal motion commands may be performed after the brake
releases. In the same manner, when the RGM drive is disabled by the user’s controller, power is removed
from the coil and the brake will mechanically engage with an audible "click".
11.2 Manually Releasing the Brake
If the user needs to manually rotate the output plate of the RGM unit when no power is available to electrically
release the brake, it is possible to manually release it. Remove the 3 screws and the blue rear cover as shown
in Figure 1: Removing the Rear Cover of an RGM.

Using a thin diameter tool, push downward on the brake release button to compress the spring below it (see
"Push to release the RGM's brake." (
p. 18)). As long as the button is held downward to keep the spring
compressed, the user may manually rotate the unit to desired position.
