„Fix“ settings:
Here the drive is constantly operated with the same preset acceleration. The final speed must be
determined with the help of parameter 953.
Example setting 05: Here the drive is set to highest dynamic. This setting will always be maintained.
Example setting 13: Here the drive receives an inert (slow) setting. This setting will always be
maintained.

With PWL2 only.
With the help of this parameter the characertistic of the drive can be set further. Here, mainly the
maximum drive speed is determined:
00 Automatik: Here the settings for acceleration and final drive speed are made on the basis of the
applicator settings.
01 100%: Here operation is effected with maximum dynamics and maximum final drive speed.
02 95%:
03 90%:
04 85%:
05 80%:
06 75%:
07 70%:
08 65%: Dynamics and final drive speed are reduced. This will enable a gentle treatment of the label
web.
Example settings:
Label lengths of more than 200 mm and a dispensing speed over 40 meters/min should always be
dealt with using a quite hard fix setting. The reason for this is a quite small loop supply of approx.
250 mm. If a slow setting is used here some kind of blocking may easily result.
For highest dynamic at highest speed the following parameter setting must be chosen:
