Joint Torque monitor by ROS

Hello. We are using ABB robot IRB120 and I need to get the joints motors torque, so is there a way to get the values using a certain rostopic or service from the ABB package. I know that there is a function in RAPID programming. But if there’s no direct way to get the joint torque, is there a way to get the value from the RAPID to ROS ?
Thanks in advance

GetMotorTorque is used to read the current torque of the robot and external axes motors.

GetMotorTorque is primarily used to detect if a servo gripper holds a load or not.

Basic examples

The following example illustrates the function GetMotorTorque.

Example 1

VAR num motor_torque2;

motor_torque2 := GetMotorTorque(2);

The current motor torque of the second axis of the robot is stored in motor_torque2.
