7 STARTUP AND OPERATION
NOTICE
Operating voltage excessively high or incorrectly connected!
Operating voltages that are too high or incorrectly connected can cause damage to the
L-412.xx9025E1.
► Pay attention to the
L-412.xx9025E1.
► Pay attention to correct
NOTICE
Unintentional change in position due to missing self-locking!
The L-412.xx9025E1's drive does not have self-locking. For the models of the L-412 without
holding brake, the following therefore applies:
The L-412.xx9025E1 can move unintentionally when the servo control is switched off, e.g.,
when deactivating the servo mode or switching the electronics off. Unintentional changes in
position can damage the L-412.xx9025E1, the load to be moved, and the surroundings.
► If you want to operate the positioner with a vertically or obliquely aligned motion axis:
Attach suitable gravity compensation (not included in the scope of delivery).
► Before switching off or rebooting the controller, take suitable precautionary measures to
ensure that unintentional changes in the position of the motion platform are not possible.
NOTICE
Damage due to collisions!
Collisions can damage the L-412.xx9025E1, the load to be moved, and the surroundings.
► Stop the motion immediately if an electronics malfunction occurs.
► If possible, adapt the travel range limits of your mechanical system in the software that
you use for commanding the motion.
NOTICE
Uncontrolled oscillation!
Oscillation can cause irreparable damage to the L-412.xx9025E1. Oscillation is indicated by a
humming noise and can be caused by the following:
■ The load and/or dynamics during operation differ considerably from the calibration
settings.
► If you notice oscillation, stop the L-412.xx9025E1 immediately.
L-412.xx9025E1 Startup
1. Start the electronics (refer to the user manual for the electronics).
2. Configure the electronics for the L-412.xx9025E1 during startup:
■ Configure the electronics using the parameters of the L-412.xx9025E1.
3. Start a few motion cycles for testing purposes (refer to the user manual for the
electronics).
