3.3.4 Connector properties
All connections of the servo drive system (except the ground bolt) are plugging style
connectors. This makes it easier to install the cables and to replace a drive. Never the less
it also opens the possibility to create cable sets for high volume machines.
The mechanical properties of the interface connectors are:
