E-Stop Operational Considerations - Omron LD-250 Assembly Instructions Manual

3.13 E-Stop Operational Considerations

Engaging the E-Stop through the external connector (or Operator Panel) faster than 250 ms
causes the drive motors to re-engage when you release the E-Stop. Motor re-engagement
occurs because the LD-250 Core is designed to receive a consistent E-Stop signal for at least
250 ms. Signals that engage and disengage in under 250 ms cause the LD-250 Core to
interpret the signal as a bumper press, which automatically re-engages the motors.
No signal on the E-Stop chain can cause the robot to operate while the E-Stop remains
engaged. Thus, you must keep the E-Stop engaged, if your intent is to keep the AMR in an
E-Stop state.
