Torque-controlled mode
To activate the torque-controlled mode, the Commands windows has to be configured accordingly.
The torque setpoint can be specified in
A
or
Nm
. This can be done with the help of the menu item
Options/Display units
. The associated menus will then automatically adopt the selected unit.
If you want to use the unit Nm for the torque, you have to make the
torque constant
known, i.e. the
conversion factor between the current and the torque. The torque constant has to be entered into the
menu
Parameters/Device parameters/Motor data
and can be calculated using the information stated
on the type plate of the motor. Divide the rated torque by the rated current.
A torque constant of
0 Nm/A
is not permissible if "torques in Nm" has been selected.
4.2 Setpoint assignment through setpoint selectors
The DUET_FL servo positioning controller allows you to assign the setpoint through a setpoint
management system in the torque control and speed control mode. You can find the corresponding
menu under
Operating mode/Setpoint-Selection
. The following setpoint sources can be selected:
2 analog inputs:
AIN 0 and AIN 1 (parameterization see
chapter Analog inputs AIN0 and AIN1
Fixed value RS232
Fixed value CAN
Position controller (in speed control mode)
Speed controller (in torque control mode)
If no setpoint source is active, the setpoint is zero.
The setpoint management system manages your settings separately for the individual operating
modes. This means that when you change the operating mode, the setpoint selector will be
automatically set to the values defined last by you in the respective operating mode.
