Torque Mode 

In torque mode, the motor is commanded to run with fixed torque output. The velocity varies depending 
on  the  actual  load.  The  motor  runs  as  fast  as  it  can  for  a  certain  load  situation.  In  this  mode,  the 
commutation angle is always 90 degrees ahead for maximum torque output. 
 
With axis parameter 14, the 

target phase current amplitude

 can be configured [mA] to the desired value. It 

is fixed as long as the motor is running in torque mode. The current amplitude will not be regulated. The 
range of axis parameter 14 covers the maximum current range allowed by the TMCM-1311, which is up to 
4200mA peak phase current. The moving direction is defined by the sign of axis parameter 14.

OW TO USE TRAPEZOID RAMPS IN TORQUE MODE

: 

-

 

Set  the 

current

 

slope

  with  axis  parameter  20.  This  way,  trapezoid  ramps  with  acceleration  and 

deceleration of the drive can be generated.  

-

 

Set a 

start and stop value

 for the ramp using axis parameter 141.  

-

 

To  get  the  actual  state  of  the  ramp,  the 

actual  current  in  torque  mode

  can  be  read  out  with  axis 

parameter 19. This parameter can also be set to specify a value for the actual current, if necessary.

provides 

information on the actual advance angle 
(in these cases the unit is microsteps).
