Detailed Description
2.4 Closed-loop control
Velocities, Setpoint/Actual-Value Systems, Closed-Loop Control (G2)
2-54 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
2.4.2 Parameter sets of the position controller
Six different parameters sets
The position control can operate with 6 different servo parameter sets.
They are used as follows
1. Fast adaptation of the position control to altered machine characteristics during operation,
e.g. a gear change of the spindle.
2. Matching the dynamics of an axis to another axis, e.g. during tapping.
Parameter set changeover
The following machine data can be changed by switching over the parameter set during operation:
Denominator load gearbox MD31050 $MA_DRIVE_AX_RATIO_DENOM[n]
Numerator load gearbox MD31060 $MA_DRIVE_AX_RATIO_NUMERA[n]
