A servo actuator controlling system includes a master controller and a number of servo actuators coupled to at least one interface of the master controller. The master controller includes a master MCU and a number of interfaces connected to the master MCU via a first bus. Each servo actuator includes a servo MCU, a first interface coupled to the servo MCU via a second bus, a second interface coupled the first interface and the serve MCU, a first servo switch connected between the first interface and the servo MCU, and a second servo switch connected between the second interface and the servo MCU. The first servo switch is set to turn on or off the first interface and the second servo switch is set to turn on or off the second interface.

A servo actuator default disconnected ID setting method is performed by a servo actuator controlling system, which includes a plurality of servo actuators. A first message is broadcasted which indicates that an original ID is replaced with a non-default-disconnected to the plurality of servo actuators. The original ID of each actuator is replaced with the non-default-disconnected according to the first message. A second message is broadcasted which indicates that the non-default-disconnected ID is replaced with a default disconnected ID. And the non-default-disconnected ID of each servo actuator is replaced with the default disconnected ID according to the second message.

A first drive acts on a machine element via a transmission and a second drive acts on the machine element directly. First and second closed-loop speed controllers determine respective first and second setpoint force values for the first and second drives with the aid of the difference between the setpoint speed value and of the actual speed value and activate the first drive and/or the second drive as a function of the respective first and second setpoint force values. Respective first and second pilot force values are determined from a first axis inertia scaled by a first scaling factor (), and second axis inertia scaled by a second scaling factor (1).

A servo actuator ID setting method is performed by a servo actuator controlling system. The servo actuator controlling system includes a master controller and a plurality of servo actuators. One servo actuator is set to disconnect to a next servo actuator. A plurality of interfaces of the master controller are selected to turn on in sequence. The following steps are repeatedly performed to set servo actuator ID: broadcasting a signal to replace an original ID of each of the plurality of servo actuators with a target ID; the plurality of servo actuators in each branch connecting to the master controller; and replacing the original ID of each of the plurality servo actuator with the target ID.

A servo actuator default disconnected ID setting method is performed by a servo actuator controlling system, which includes a plurality of servo actuators. A first message is broadcasted which indicates that an original ID is replaced with a non-default-disconnected to the plurality of servo actuators. The original ID of each actuator is replaced with the non-default-disconnected according to the first message. A second message is broadcasted which indicates that the non-default-disconnected ID is replaced with a default disconnected ID. And the non-default-disconnected ID of each servo actuator is replaced with the default disconnected ID according to the second message.

A method for controlling a manipulator system including a manipulator, several drives and a mobile platform. A first converter for actuating at least two of the several drives is associated with the manipulator system. The method includes the steps of: a) identifying one of the drives of the manipulator system that is associated with the first converter and that must be used to travel over a current planned movement path of the manipulator system, and (b) actuating the one identified associated drive by means of the first converter, where the actuated drive is for the manipulator system to travel over the planned movement path. One of the at least two drives that is not being actuated is stationary preferably fixed or secured by a mechanical brake.
