The process values are sent as cyclic data, with an updating frequency decided
by the application engineer. The data enables the control system to have access
to basic information such as speed, current, torque and diagnostic information.
A setpoint for speed or torque, in percentage or absolute values can be sent. It
is also possible to give commands to the drive, for example, start, stop and fault
reset.
