Chapter 6 Control Modes of OperationASDA-B Series

6.5Control Modes Selection

Except signal control mode operation, ASDA-B series AC drive also provide S-P, S-T, T-P these three multiple modes for the users to select.

1） Speed / Position mode selection: S-P

2） Speed / Torque mode selection: S-T

3） Torque / Position mode selection: T-P

Table 6.G

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

S-P Mode:

The command source of S-P 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:

In position mode (when S-P is ON), the motor will start to count pulse and operate following the external pulse command. When switching to the speed mode (when S-P is OFF), it will stop counting pulse even if the pulse command is continuously sent out. The speed command is determined by SPD0~1 and the motor will rotate following the command. After S-P is ON again, it will immediately return to position mode.
