-Potentiometer Xp linksdrehen bis die Schwingung abklingt,
-Xp-Poti noch 2 Stellungen weiter nach links drehen.
Drive behaviour:
Amplification too low
long oscillations 1... 0.1Hz
long overshoots
overruns target position
Caution:
in case of operating with CNC\PLC
-in case of maximum speed
-adjust command value speed with Poti n

390kW decrease with R9 (47kW up to 220kW)
= 22nF increase with C4 (0,1mF up to 1mF)
to 50%
P
= 0
= 50% (turning clock-wise increases amplification)
= default values
Amplification too high
short oscillations 30 ... 200Hz
vibrates during acceleration,
vibrates during braking and in position
