7.3.3 Analog Signal Processing
In the analog – torque mode, external analog command signals are directly inputted to the current loops
in the driver, thus directly controlling target current through the internal current loop. Analog signal is
processed in the same way as that in the analog – speed mode.
In the analog – torque mode,
