6.5Control Modes Selection

Except signal control mode operation, ASDA-AB series AC drive also provide Pt-S, Pr-S, S-T, Pt-T, Pr-T these five multiple modes for the users to select.

1） Speed / Position mode selection: Pt-S, Pr-S

2） Speed / Torque mode selection: S-T

3） Torque / Position mode selection: Pt-T, Pr-T

Mode	Name	Code	Description
	Pt-S	06	Either Pt or S control mode can be selected via the Digital Inputs (DI)
	Pt-T	07	Either Pt or T control mode can be selected via the Digital Inputs (DI)
Dual Mode
	Pr-S	08	Either Pr or S control mode can be selected via the Digital Inputs (DI)
	Pr-T	09	Either Pr or T control mode can be selected via the Digital Inputs (DI)
	S-T	10	Either S or T control mode can be selected via the Digital Inputs (DI)

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). In position mode, we recommend that the users can use Pt mode to input pulse to reduce the use of DI inputs (POS0~2).

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 / Pr-S Mode:

The command source of Pt-S mode is from external input pulse. The command source of Pr-S mode is from internal parameters (P1-15 to P1-30). 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 selection will be more complicated when the position of Pr-S mode and speed command are both selected through DI signal.

The timing chart of speed / position control mode selection is shown as the figure below:
