CAUTION
doors closed during operation. To reduce inconvenience, we sug-
gest to use ear protection if cabinet doors must be opened during
normal operation.
The device shuts down in case of excessively high temperature
in the control cabinet. Make sure sufficient forced ventilation is
supplied within the control cabinet.
Maximum 100 m total cable length per string.
Limited by fieldbus protocol.
Maximum 14 axes for string 1, total maximum 28 axes if string 1
and 2 are combined (observe total power and current restric-
tions).
Maximum 14 per string, total maximum 28 on strings 2 and 3,
(observe total power and current restrictions).
Use coincidence factor of the axes for distribution and system
power optimization.
