6.5.2 Speed / Torque dual mode
Speed / Torque dual mode includes only the S-T mode. You control the Speed command with
the external analog voltage and the internal parameters (P1.009 – P1.011), which you select with
DI.SPD0 – DI.SPD1. Similarly, the source of the Torque command can be the external analog
voltage or the internal parameters (P1.012 – P1.014), and is selected by DI.TCM0 – DI.TCM1.
The switch between Speed and Torque mode is controlled by DI.S-T (0x19) signal. The timing
diagram is shown below.

Figure 6.5.2.1 Speed / Torque dual mode
In Torque mode (DI.S-T is on), you select the Torque command with DI.TCM0 and DI.TCM1.
When switching to Speed mode (DI.S-T is off), you select the Speed command with DI.SPD0
and DI.SPD1. The motor operates according to the Speed command. When DI.S-T is ON, it
returns to the Torque mode. Please refer to the introduction of single mode for the DI signal and
the selected commands for each mode.
