Interpolation algorithm

• If "Linear interpolation" or "Quadratic interpolation" has been selected and no feedforward control values for

speed and torque/acceleration are transmitted, it is wise to generate the feedforward values by differentiation

of the position signal (C02681, C00276).

• If "Optimized mode 1" has been selected, the feedforward control values in the application are differentiated

from the set position in the grid of the bus cycle time and then linearly interpolated to the control cycle.

(No additional differentiation functions required.)

Interpolation cycle time

• For the communication via system bus (CANopen), the sync cycle time must also be parameterised in code
