Abstract
An actuator (1M, 1S) with a motor (12) and a motor controller (11) is configurable to operate as a master or a slave to another actuator which is coupled mechanically for driving a common load. For the case where the actuator (1M) is set as the master, the motor controller (11) receives on an input terminal (Y3) an external position control signal (pC), generates a motor control signal (sC) for controlling the motor (12) based on the position control signal (pC), and supplies the motor control signal (sC) to an output terminal (U5) for controlling a slave. For the case where the actuator (1S) is set as the slave, the motor controller (11) controls the motor (12) by supplying to the motor (12) the motor control signal (sC) received from the master. Controlling the actuators with a master improves workload balancing and reduces damages to transmission mechanics of the actuators.
