Hydraulic/electrical interpolation

Objective
Contour precision is achieved with a drive dynamic response, which is set the same for all of
the axes involved. The statement applies to both hydraulic and electric drives.
In addition to identical K
controller is "identical".
Implementation
A velocity setpoint filter of the faster axis (e.g. electric) must be set to the difference between
the time constants of the velocity control loop (T

When dynamic servo control (DSC) is active, the DSC function must be activated on all
interpolating axes.
