With the %-specification the drive behaviour with respect to acceleration and deceleration can be
preset. 100 % corresponds to hard acceleration and deceleration, 30 % corresponds to a very low
acceleration and deceleration.
With using the drive as an unwinder with loop control the setting usually should be around 45 %.
With a 100 %-setting there is a risk of the sleeve getting tangled up due to the hard acceleration and
deceleration.

9.12.17 952 Loop unwinder
With PWL2 only.
There are two parameters for setting the characeristic of the loop unwinder since in extreme cases
large label feeds at high speed, or small labels with occasional transport must be dealt with.
Enter the mode of the loop unwinder as follows:
00 Standard: With the standard setting the loop unwinder is set and optimised automatically. After
switching on or after pausing for an extended period of time the control is set to its highest dynamics,
i.e., even with small label feeds and little output the drive will run roughly in the beginning. On the other
hand, however, after a loong phase of ittle output and sudden high performance the loop may not be
able to be built up in time.
01 Automatic: Based on the operating mode and the set maximum speed of the applicator the loop
unwinder is preset with respect to acceleration and maximum speed. The loop unwinder will optimise
itself automatically to the current process during operation.
02 Fast: With respect to final speed and acceleration the drive is set to high discharging speed. During
operation the drive will optimise itelf for the actual requirment.
03 Medium: As 02, but for middle speed range.
04 Slow: As 02, but for low speed range.
