Cyclic synchronous torque mode (IEC 61800-7)
156 L EDS94TA11010xxxx EN 1.2 - 03/2010
3.14 Cyclic synchronous torque mode (IEC 61800-7)
This operating mode provides a fast torque follower with speed limitation. The torque
profile to be processed is defined by the master control.
Subfunctions of the operating mode
Calculation of the torque setpoint
Interpolation between communication cycle and control cycle
Torque control
Limitation of the motor speed
Update of the actual values for position, speed, and torque
Selection of operating mode
The "Cyclic synchronous torque mode" is selected using the value "10" via the 0x6060
object (mode of operation).
