The LECP7-XB3 is a controller for LE's 24VDC step motors. It is similar to the LECP6 controller, with the addition of a battery backup. The motor position signal can be monitored immediately after power is shut off or lost, regardless of the actuators operation. A return to origin is not required after power recovery. The nickel hydride battery has a 72 hour recharging time, up to 20 days of position retention, and a 2-yr replacement life.
