Load control system and load driving system

A load control system comprising:

• a plurality of drivers provided correspondingly to a plurality of actuators in order to control driving of the respective actuators for driving loads, each of the plurality of drivers including a control unit that controls the actuator directly associated with a subject driver and generates a command signal for controlling the driving of an actuator directly associated with all or a portion of other drivers in the plurality of drivers excluding the subject driver, the respective drivers being electrically connected to one another;
• and
• a mutual control communication state, in which the control unit of each of the plurality of drivers transmits to the control units of the all or the portion of other drivers in the plurality of drivers excluding the subject driver the command signal for controlling the driving of the actuator directly associated with the all or the portion of other drivers,
• wherein the control unit of each of the plurality of drivers is formed such that, when one of the plurality of drivers is replaced with a replacement driver, and another one of the plurality of drivers excluding the replaced driver generates to the replacement driver the same command signal as the command signal for the replaced driver, the actuator directly associated with the replacement driver executes the same predetermined operation as the actuator directly associated with the replaced driver.
