6.5 Control Modes Selection
Except signal control mode operation, ASDA-B2 series AC drive also provide PT-S, S-T,
PT-T, these three multiple modes for the users to select.
1） Speed / Position mode selection: PT-S
2） Speed / Torque mode selection: S-T
3） Torque / Position mode selection: PT-T
Mode Name Code Description
Dual Mode
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)
S-T 0A
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).
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:
