Sz and Tz mode selection is not provided. In order to avoid using too much DI inputs, we recommend that
user can use external analog signal as input command in speed and torque mode to reduce the use of DI
inputs (SPD0~1 or TCM0~1). In position mode, we recommend that users can use Pt mode to input pulse to
reduce the use of DI inputs (POS0~2).
Please refer to table 3.H and table 3.I in section 3-3-2 to see the default DI/DO signal in different modes.
