ASDA-A2  Chapter 6  Control Mode of Operation 
Revision February, 2017  6-45 
6.4 Torque Mode 
Torque control mode (T or Tz) is appropriate in torque control application, such as printing machine, 
winding machine, etc. There are two kinds of command source, analog input and register. Analog 
command input uses external voltage to control the torque of the motor while register uses the 
internal parameters (P1-12~P1-14) as the torque command. 
 
6.4.1  Selection of Torque Command  
Torque command source are external analog voltage and parameters. It uses CN1 DI signal for 
selection. See as below.

T4 1 1  P1-14 
  The status of TCM0 ~ TCM1: 0 means DI OFF and 1 means DI ON. 
  When TCM0 = TCM1 = 0, if it is in Tz mode, then the command is 0. Thus, if there is no 
need to use analog voltage as torque command, Tz mode is applicable and can avoid the 
problem of zero drift. If it is in T mode, the command will be the voltage deviation between 
T-REF and GND. Its input voltage range is -10V~+10V, which mean the corresponding 
torque is adjustable (P1-41).  
  When neither TCM0 nor TCM1 is 0, parameters become the source of torque command. 
The command will be executed after TCM0 ~ TCM1 are changed. There is no need to use 
CTRG for triggering. 
The torque command can be used in torque mode (T or Tz) and speed mode (S or Sz). When it is 
in speed mode, it can be regarded as the command input of torque limit.
