Basic function "Position follower"

The "Position follower" basic function based on the "Interpolated position mode" serves as

setpoint interface for position-controlled drives.

 The specified position setpoint can either refer to the encoder on the motor side or to

the (position) encoder used additionally to detect the machine position. The selection

of the encoder configuration serves to adapt the internal control structure accordingly.

 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.

 The speed can also be precontrolled with the position setpoint by a corresponding

selection in C02681. Then, the speed is calculated by differentiation of the position

setpoint.
