Notes on the electrical connection
NOTICE!
Electrostatic discharges to the Motion Control Systems connections can damage the elec-
tronic components.
Observe the ESD protective measures.
NOTICE!
Incorrect connection of the wires can damage the electronic components.
Connect the wires as shown in the connection assignment.
NOTICE!
A short-term voltage peak during braking can damage the power supply or other con-
nected devices.
For applications with high load inertia, the FAULHABER Braking Chopper of the BC
5004 series can be used to limit overvoltages and thereby protect the power supply. For
more detailed information see the data sheet for the Braking Chopper.
The Motion Control Systems contain a PWM output stage for controlling the motors. Power
losses arising during operation and alternating electrical fields arising due to the pulsed
control of the motors, must be dissipated and damped by appropriate installation.
Connect the Motion Control System to an earthing system. This should be done prefera-
bly by mounting it on an earthed base plate, or alternatively by connecting it to an
earthed flange. Alternatively the earthing can be achieved by shielding the connecting
cables to the connection sockets.
Make sure that potential equalisation is present between all coupled parts of the sys-
tem.
If several electrical devices or controllers are networked by means of RS232 or CAN,
make sure that the potential difference between the earth potentials of the various
parts of the system is less than 2 V.
The EGND connection, and if necessary the shielding around the supply connection, are
available for potential equalisation.
