62.12 AdaptKpMax (speed controller p-part adaption, maximum p-part)
Proportional gain of the speed controller with maximum diameter (larges coil).

62.13 AdaptKpOutDest (speed controller p-part adaption, destination of output value)
Index pointer to the sink for speed controller p
-part adaption output value. The format is xxyy, with: xx =
group and
yy = index.
As default,
nothing is connected to the output.

62.15 AdaptKpSPC (speed controller p-part adaption, adapted p-part output)
Output of the speed controller p
-part adaption. Calculated actual p-part of the speed controller depending on
the coil diameter.
The adapted p
-part is automatically written onto KpS (24.03) when the speed controller p-part adaption is
released, see
AdaptKpOutDest (62.13).

The actual acceleration adjust filters e.g. the dv_dt (2.16) output of the ramp with a PT1-filter. The output has to be 100 %
with maximum acceleration using the shortest ramp time. To achi
eve this goal a trimming input is available.
Commissioning hint:
−
AccTrim (62.19) has to be determined with acceleration trials. AccActAdjust (62.21) has to be 100 % with maximum
acceleration using the shortest ramp time.
− Autotuning is possible with WinderTuning (61.21) = InerMechComp.
62.17 AccActIn (actual acceleration adjustment, actual acceleration input)
Source (signal/parameter) for the actual acceleration input of the actual acceleration adjustment. The format is
-
xxyy, with: - = negate input, xx = group and yy = index.
Default setting of 216 equals
dv_dt (2.16).

Inertia compensation (acceleration compensation):
During the winding operation, the motor must only generate the torque for the needed tension. For acceleration, an
additional torque is necessary. The acceleration
torque (inertia compensation) depends on the inertia of the complete
winder (motor, gearbox, spool and coil). The inertia of motor, gearbox and spool is constant. The inertia of the coil is a
function of the diameter. In case the diameter is small, the ine
rtia is small. With increasing diameter, the inertia increases.
That means more acceleration torque (inertia compensation) is needed. The problem in many applications is that the
inertia is not available. Thus, it has to be determined by means of acceleration tests.
