The inertia compensation calculates the acceleration torque needed to compensate the inertia of the winder mechanics
plus the inertia of the coil. To adapt the inertia of the coil its diameter and width is needed.
Commissioning hint:
−
InerMech (62.26) has to be determined by means of acceleration trials with maximum acceleration using the shortest
ramp time. Only the spool is on the winder. The result is available in MotTorqFilt (1.07) during the acceleration.
Autotuning is possible with WinderTuning (61.21) = InerMechComp.
−
InerCoil (62.25) has to be determined by means of acceleration trials with maximum acceleration using the shortest
ramp time. The largest coil (maximum diameter and maximum width) has to be on the winder. The result is available in
MotTorqFilt (1.07) during the acceleration.
Autotuning is possible with WinderTuning (61.21) = InerCoilComp.
−
Do not forget to subtract the average friction losses from the measured values - see FrictAt0Spd (63.26) to
FrictAt100Spd (63.30).
−
The width calculation works with relative width’ in percent of the maximum width, so the physical values must be
converted.

InerReleaseCmd (62.28) releases InertiaComp (62.30). The output is forced to zero if the switch is open.
62.23 InerDiaActIn (inertia compensation, actual diameter input)
Source (signal/parameter) for the actual diameter input of the inertia compensation. The format is xxyy, with:
xx = group and yy = index.
Default setting of 6208 equals DiameterAct (62.08).
