Sz and Tz mode selection is not provided. In order to avoid using too much DI inputs, we
recommend that the users 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).
Please refer to table 3.B and table 3.C in section 3.3.2 to see the default pin number of
DI/DO signal.
6.5.1 Speed / Position Control Mode Selection
PT-S Mode:
The command source of PT-S mode is from external input pulse. The speed command
can be the external analog voltage or internal parameters (P1-09 to P1-11). The speed
and position mode switching is controlled by the S-P signal. The timing chart of speed /
position control mode selection is shown as the figure below:
