7.10 Cyclic sync torque mode (cst)
This operating mode provides a quick torque follower with speed limitation. The torque profile to
be processed is defined by the controller.
Subfunctions of the operating mode
• Torque control with speed limitation
• Calculation of the torque setpoint
• Interpolation of the setpoints from the communication cycle to the control cycle
• Limitation of the motor speed
• Update of the actual values for position, speed, and torque
Selection of the operating mode
"Cyclic synchronous torque mode" is selected with the setting "10" in
0x6060 (or 0x6860 for axis B).

Note!
• This operating mode can only be actuated reasonably if the servo control is set as
motor control.  Motor control & motor settings
• Since this is a cyclic mode, setpoints in the bus cycle are expected.
• If communication is interrupted and thus telegrams fail to appear, the internal "quick
stop" function takes over the braking of the motor. Afterwards, the controller is
inhibited.
