• A specification will often state the required stroke for the application. What is frequently seen is that units are damaged by not following a simple requirement stated in the Installation Manual. Best practices dictate the utilization of End of Travel (EOT) sensors used with actuators and drives. This is done to prevent the actuators from striking the mechanical stops at each end, and typically a manual will clearly show where these sensors should be placed on the device. Actuators do have built in "bumpers" to help absorb energy when the mechanical stops are struck, but they are not designed to provide unlimited protection against repeated strikes.

  • Frequently, servo motors are returned where the brakes are worn. This is almost always due to the brake being applied repeatedly while the motor/load is moving. The application of a motor brake in a "dynamic / moving" scenario will result in dramatic wear of the brake mechanism.
