Connection at the supply side
Connections at the supply side:
Discrete inputs and outputs (for instance for discrete target values preselection or for
connection of limit switches / reference switches)
Communication connections
Make sure that the connection cables to the connection side are not longer than 3 m.
Keep the screen connections for connection cables short and flat.
To reduce the effects on the DC power supply network, ferrite sleeves (such as WE 742 700
790) can be fitted on the supply cables.

Power supply
Connect the Motion Controller to a sufficiently well dimensioned power supply unit.
During acceleration procedures, current peaks with values up to the peak current limit
setting of the motor can occur for multiples of 10 ms.
During braking procedures, energy can be regenerated and fed back into the DC power
supply network. If this energy cannot be taken up by other drives, the voltage in the DC
power supply network will rise. A limit value for the voltage that can be fed back dur-
ing regenerative braking can be set in the Motion Controller. Alternatively the overvolt-
age can be dissipated by an additional external Brake Chopper, see the datasheet for
the Brake Chopper.
The USB port is a pure configuration connection. A cable length of < 3 m also applies
to the USB connection.
