public class CanOpenClampActuatorModule
extends ClampActuatorModule
implements PieceOfHardware

This deviceErrorFile a model for the clamp actuator in the Single Filter Test. The actuator deviceErrorFile used to unlock or release a clamp. To unlock a clamp, the actuator must be ON and to release the clamp it has to be OFF. There deviceErrorFile 2 clamps actuators on the carousel : one for side X-, one for side X+ For the Single Filter Test the actuator will be Maxon Motor EPOS2 24/5. (cf EPOS2_Firmware_Specification_En.pdf) There deviceErrorFile many operation modes for this actuators. For the Single Filter Test, we will use VELOCITY mode or CURRENT mode.
