9.9 Torque follower
This basic function is used as setpoint interface for torque-controlled drives.
r The motor control is automatically changed over to torque control with speed
limitation.
r As an option, an internal interpolation of the torque setpoint can be carried out in order
to specify the setpoint with reduced cycle rates without the drive behaviour being
unsteady. The detection of the cycle rate and the synchronisation of the setpoint
transfer is carried out automatically.
r If the direction of rotation of the motor must be inverted due to the mounting position
of the motor or the existing gearbox ratio the use of the control signals can be changed
over accordingly via parameter setting.
9.9.1 Signal flow
[9-3] Signal flow - torque follower
Internal variables of the motor control (oscilloscope signals)
r The red numbers specified in the signal flow represent internal variables of the motor
control, which can be recorded with the Oscilloscope
for diagnostic and documentation
purposes.
