6.5.4.19 DD_ReadParameter4_ISD51x
This function block asynchronously reads general objects
of up to 4 bytes from the object dictionary of the axis if
the Enable input is set. For the index and sub-index of the
parameters, see chapter 7 Servo Drive Parameter Description.
The output data is read from the device and is therefore
not immediately available.
