Electrical installation
This chapter provides all of the relevant information for the electrical installation of the
BL 4100-C servo drive with an integrated "Safe Torque Off (STO)" safety function.
13.1
Notes concerning the safe and EMC-
compliant installation
13.1.1
Explanations and terminology
Electromagnetic compatibility (EMC) or electromagnetic interference (EMI) includes the
following requirements:
l
Sufficient
immunity
of an electrical installation or an electrical device against
external electrical, magnetic or electromagnetic interferences via cables or the
environment.
l
Sufficiently small
unwanted emission
of electrical, magnetic or electromagnetic
interference from an electrical installation or an electrical device to other devices in
the vicinity via cables or the environment.
13.1.2
General information about electromagnetic
compatibility
The interference emission and interference immunity of a servo drive always depend on
the overall drive concept consisting of the following components:
l
Power supply
l
Servo drive
l
Motor
l
Electromechanical system
l
Configuration and type of wiring
l
Superordinate control system
In order to increase interference immunity and to decrease interference emissions, the
servo drive has integrated filters so that it can be used without additional shielding and
filtering devices in most applications.
