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
v
settings, it must be ensured that the step response of the velocity
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
v, ers
)
T

= T

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