Parameter setting & configuration
Cyclic synchronous torque mode (IEC 61800-7)
3.14.7 Basic function "Torque follower"
The "Torque follower" basic function based on the "Cyclic synchronous torque mode"
serves as setpoint interface for torque-controlled drives.
 The motor control is switched over automatically to torque control with speed
limitation.
 If the direction of rotation of the motor must be inverted due to the mounting position
of the motor or the gearbox ratio available, the use of the control signals can be
accordingly changed over by means of parameterisation.
 A stable speed limitation requires a minimum difference of the speed limit values of 50
rpm. If the defined speed limit values fall below this minimum difference, the internal
lower speed limit value is lowered accordingly. The upper speed limit value remains
unchanged. Signal flow
