1417:8 n_x for 'n_act < n_x' signal
Min Standard
0.0 120.0
0.0 6000.0
The threshold speed or the threshold velocity (SLM) for the output signal "n_act < n_x" is de-
fined using this parameter.
1418:8 n_min for 'n_act < n_min' signal
Min Standard
0.0 0.3
0.0 5.0
The threshold speed or the threshold velocity (SLM) for the output signal "n_act < n_min" is de-
fined using this parameter.
1421:8 Time constant, integrator feedback (n controller)
Min Standard
0.0 0.0
The integrator of the speed controller is re-parameterized via a feedback element to a PT1 filter
(1st order lowpass characteristics). The PT1 filter time constant can be set via P1421.
The following is valid:
P1421 < 1.0 ––> the PT1 filter is not active, the pure integrator is effective
P1421 >= 1.0 ––> the PT1 filter is active and has replaced the pure integrator
Applications:
Movement at zero setpoint with a dominant stiction can be suppressed but with the disadvan-
tage that a setpoint-actual value difference remains. This can result in, for example, an oscilla-
tion of a position-controlled axis at standstill (stick-slip effect) or overshoot with micrometer
steps.
Prevents excessive stress for axes which are mechanically rigidly coupled (e.g. for synchronous
spindles, master-slave axes).
1426:8 Toler.bandwidth f.'n_set = n_act' signal
Min Standard
0.0 1.0
0.0 20.0
The tolerance bandwidth for the "n_set = n_act" output signal is defined using this parameter.
