The torque command processing unit is to select torque command source according to Section
6.4.1, including the S-curve setting for torque command. The current control unit manages the
gain parameters of the servo drive and calculates the current for servo motor in time. Since the
current control unit is very complicated, and is not relevant to the application. There is no need to
adjust the parameters, so only command end setting is provided.
The torque command processing unit is as the following
figure.
