To activate the compensator the threshold which is to be
set C94 must be decreased so that the dancer-Position
controller be activated. With the setting of Cl 94 = 100 %
(factory setting) the compensator is disconnected from
the dancer-Position controller.
9.10.1 Reset of the compensator
The compensator be reset (e.g. after finishing the
winding process) via a freely assignable digital input, the operating
unit, or the LECOM
Select the freely assignable terminal which is to be assigned to the
function “diameter compensator reset” via Cl 12. This function
is assigned to the freely assignable terminal Cl 13. If
the compensator is enabled via the freely assignable
terminal, the thresholds will be compared first. When activating the
“diameter compensator reset”, the counter value is set to
After
mains connection, the compensator is set to
Caution!
If the controller is enabled when the compensator is reset,
then the counter value is set to zero immediately. Thus, with a high
compensator when activating the “diameter
compensator reset” the value which is of the

This may lead to high accelerations and the
limiting function may be activated.
The integration time be set Cl 95 (unit [s]), and the
decrement time be determined Cl96 (unit
If the output of the dancer-Position controller falls below the
threshold set Cl 94 after the compensator has
already been activated, the correction value of the
