SINUMERIK 840D/SIMODRIVE 611 digital Descr. of Functions HLA Module (FBHLA) – 04.00 Edition
0...7 index of the parameter set
Minimum: Maximum:
0.2 1.0
Input of damping for feedforward control filter 1 (PT2 low-pass) in force control-
ler.
0...7 index of the parameter set
Minimum: Maximum:
10.0 7999.0
Input of blocking frequency for feedforward control filter 1 (band-stop) in force
controller.
0...7 index of the parameter set
Minimum: Maximum:
5.0 7999.0
Input of –3 dB bandwidth for feedforward control filter 1 (band-stop) in force con-
troller.
0...7 index of the parameter set
Minimum: Maximum:
0.0 7999.0
Input of numerator bandwidth for feedforward control filter 1 (damped band-
stop) in force controller.
Setting a value of 0 initializes the filter as an undamped band-stop. The value
set in MD 5270 must not exceed twice the value set in MD 5269.
