The Magnetic Field Actuator (STL DCS6K, single channel)

Actuator Api

Additional Api Functions

In addition to the standard API defined for a magnetic field actuator, the DCS6K supports additional io controls that are usable for setting up the magnetic field. The parameters are those, that are used in the examples of the reference manual chapter 3.3.5.2

init_load

{
    "type": "io-control-request",
    "ioctl_name": "init_load",
    "parameters": {
        "rref": 100,
        "lref": 5.0,
        "deltaRref": 0.05,
        "deltaLref": 0.05
    }
}

Initializes the load by:

reading the reference impedance
measureing the current impedance
setting the reference impedance according to the given parameters
performing an impedance test.

Will return 0 or 1 according to the manual of the DCS6K

do_load_adaption

{
    "type": "io-control-request",
    "ioctl_name": "do_load_adaption",
    "parameters": {
        "proportional_factor": 100,
        "integral_factor": 5.0,
        "slew_rate": 0.05,
    }
}

initializes the PID
sets the PID parameters for the “standard” pid

setup_dcs6k

{
    "type": "io-control-request",
    "ioctl_name": "do_load_adaption",
    "parameters": {}
}

Sets the opration mode and startup mode to “analog”
Sets the analog parameters to 1,standard,1,0.05
