3.1.1 Hazard analysis
The machine manufacturer must produce a hazard analysis for the machine. He must take
appropriate measures to ensure that unexpected movements do not lead to hazardous situ-
ations for either people or equipment.
3.1.2 Electrical data
Please note the electrical requirements stated in the chapters entitled "Technical Details",
"Wiring" and "Function Description".
INFORMATION
A 3L line choke with u
k
= 2% must be used in the event of a mains voltage
imbalance of > 3%. Install the line choke on the mounting plate in a way that
is EMC-compliant.
3.1.3 Ambient conditions
Please note the following conditions for using the servo amplifier:
