ASDA-B2  Chapter 6  Control Modes of Operation 
Revision May, 2018     6-41 
6.5 Dual Modes 
Apart from single mode, dual mode is also provided for operation. According to Section 6.1, 
dual modes are as followings: 
(1)  Speed / Position dual mode (PT-S) 
(2)  Speed / Torque dual mode (S-T) 
(3)  Torque / Position dual mode (PT-T)

Description 
Dual Mode 
PT-S 06 PT and S can be switched via DI signal, S_P. 
PT-T 07 PT and T can be switched via DI signal, T_P. 
S-T 0A S and T can be switched via DI signal, S_T. 
Sz and Tz dual mode is not provided here. For avoiding occupying too many digital inputs 
in dual mode, speed and torque mode can use external analog voltage as the command 
source so as to reduce digital input (SPD0, SPD1 or TCM0, TCM1). Please refer to 
Chapter 3.3.2, table 3.1, Default Value of DI Input Function and table 3.2, Default Value of 
DO Output Function for the default DI / DO of each mode. 
The relationship between DI/DO signals and PIN define are set after the mode is selected. 
If users desire to change the setting, please refer to Chapter 3.3.4. 
6.5.1 Speed / Position Dual Mode 
The command source of PT-S mode is from external pulse. Speed command can be 
issued by the external analog voltage or internal parameters (P1-09 to P1-11). The switch 
of speed and position mode is controlled by the S-P signal. The timing diagram is shown 
as below:
