8.6 Adaptations
● Torque feedforward control
● Drive adaptation factor 1 ... 4: A maximum of 4 drive variables from parameter p2782[0...3]
"Mode adaptation" can be adapted.
– Kp speed controller P gain adaptation speed
– Tn speed controller integral time adaptation speed
– Current setpoint filter 1 denominator and numerator
– Current setpoint filter 2 denominator and numerator
– Speed setpoint filter 1 denominator and numerator
– Speed controller reference model natural frequency and damping
– APC / APC ECO Tv (p3769)
– APC / APC ECO filter (p3766)
Example:
For a rotary table with highly variable loading, the effective acceleration (DYNNORM) should
be adapted to the current moment of inertia. The "Intelligent load adjustment" function is used
to increase acceleration (DYNNORM) at minimal loading to 150%.
