Connection of the power supply
Discrete inputs and outputs (for instance for discrete set-point specification or for con-
nection of limit switches and reference switches)
Communication connections
Make sure that the connection cables on the connection side are not longer than 3 m.
Keep the shield 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 used on the supply cables.

Power supply
Connect the Motion Controller to a sufficiently 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
during regenerative braking can be set in the Motion Controller. Alternatively the over-
voltage can be dissipated by an additional external brake chopper, see the data sheet
for the brake chopper.
The USB port is a pure configuration connection. A cable length of < 3 m also applies
for the USB connection.
